    摘要: A self biased differential amplifier has a switching point accurately set according to a reference voltage. DC hysteresis is provided, by a circuit internal to the differential amplifier. The amplifier has an input circuit having first and second series connected transistors, wherein the beta ratio of these first and second transistors is changed by enabling an additional transistor of a hysteresis circuit according to an output state of the differential amplifier. When the output state is "high", the switching point is decreased in order that temporary small drops (due to noise or glitches) in the input signal are ignored. Conversely, when the output state is "low", the switching point is increased in order that temporary small increases in the input signal are ignored.

    摘要: A dense memory is provided which includes a one device random access memory cell using charge fill and spill techniques wherein a potential well under a storage node is filled with charge and the excess charge above a predetermined level is spilled to a diffusion or drain region connected to a sense line through a channel region controlled by pulses on a word line. One bit or two or more bits of information may be stored in the potential well at any given instant of time. Depending upon the value of the increment of voltage applied to the storage node or electrode, a given analog charge packet is stored in a potential well formed under the storage electrode. Information is read by applying a voltage to the word line to turn on the channel region and then stepping down the voltage on the storage electrode in fractional, preferably one half, increments. Charge from a charge packet spilled from the potential well under the storage electrode is detected by a sensing circuit connected to the sense line. To rewrite information into the potential well, the original increment of voltage is applied to the storage node and the sense line is pulled to ground so that the diffusion region acts as a source of charge for the potential well.

    摘要: A self-timed tri-state driver circuit for a dual-rail differential input and single-ended output is disclosed. The circuit generates a tri-state mode in response to an Output Enable (OE) input pulsing low. The OE signal input is driven high to place the driver circuit into a ready state. The circuit is maintained in a tri-state mode until data appears at the inputs. Once a data signal is received after the tri-state circuit is in the ready state, the output immediately outputs this signal. Therefore, the output of the driver is self-timed from the arrival of the data.

    摘要: A calibrated sensing system is provided in accordance with the teachings of this invention for sensing charge in a storage medium, such as a storage capacitor, coupled to an access or bit/sense line which compensates for most sources of variability in the storage medium and in the access line. In the system, the unknown charge stored in the storage medium is transferred to a first capacitor or potential well via the access line. A high charge state of the storage medium is written into the storage medium and known fractional packets of charge are prepared therefrom, transferred selectively to a second capacitor or potential well and compared with the unknown charge in the first potential to determine the relative level of the unknown charge that was stored in the storage medium. By selectively using two or more fractional packets of charge multilevel sensing is performed.

    摘要: A bucket brigade circuit is described for generating a sequence of packets of charge carriers of the form Q.sub.R /2, Q.sub.R /4, Q.sub.R /8....Q.sub.R /2.sup.N where N is an integer. The charge packets thus generated can be employed in combinations in either digital-to-analog or analog-to-digital converters. The charge generation circuit requires two equal capacitors which are used for charge redistribution. To obtain accurate quantities of charge in the generated charge packets the capacitors employed should be large, however the use of large capacitors results in low operating speed because of the large charge transfer time constants involved. The described circuit provides a scheme to reduce charge transfer time constants and therefore obtain greater speed while still permitting the use of large capacitors for high accuracy. The circuit includes a small coupling capacitor connected in series with one of the charge redistribution capacitors to produce a total capacitance which is equal to or smaller than the coupling capacitance. The sequence of charge carriers produced by the circuit can be injected into either a bucket brigade circuit or a charge-coupled-device circuit for use, for example, in digital-to-analog and analog-to-digital converters.

    摘要: A methodology is provided for reducing an arbitrary Boolean logic expression to static CMOS circuits by the use of a general matrix of P channel devices and N channel devices which are interconnected in accordance with the terms of Boolean logic expressions derived from a truth table. More specifically, from a Boolean expression a sum-of-products expression giving the 1 binary data outputs of a truth table having a 0 input is found. This is accomplished by complementing, or barring, the literals which are a binary 1 when the output is 1 and leaving true or unbarred the literals that are a binary 0. Then each input of a given product term is applied to the control gate of a P channel device, which devices are connected in series with one end tied to a source of potential and the other end of the series circuit connected to an output terminal. Each product term is arranged in parallel with other P channel device series circuits to form one half of a complete logic matrix. Similarly, for the other half of the matrix, a sum-of-products expression giving the binary 0 outputs of a truth table having a binary 1 for an input is found. Each input of a given product term is applied to the control gate of an N channel device, which devices are connected in series with one end tied to a potential reference point, such as ground, and the other end of the series circuit is connected to the output terminal. Each product term is arranged in parallel with other N channel device series circuits.

    摘要: A novel precharge circuit is provided for dynamic CMOS logic circuits which are immune to leakage currents and reduce overall power consumption. The circuit comprises a precharge transistor for precharging a node to a high voltage level indicting a first logic state during a standby mode. Thereafter, during an active mode, the node may or may not be discharged by connected logic circuitry. If the node is discharged, then an additional transistor is provided to inhibit the precharging of the already charged node during a subsequent standby mode. Similarly, if the node is not discharged, a small keeper transistor is provided to keep the node at a fully precharged level.
