摘要： An array of binary weighted capacitors, an additional capacitor having a capacitance value equivalent to that of the least of the binary weighted capacitors, a voltage comparator, switches for interconnecting the capacitors with certain predetermined voltage levels and the comparator, and a sequencing circuit are included. One side of all of the capacitors is connected to one input terminal on the comparator and the other side has applied thereto the signal to be quantized. Switch sequencing combines divided portions of a reference voltage with the signal to be quantized for presentation to the input of the comparator which thereby provides a serial digit output connected to the sequencing circuit. In this fashion, a linear conversion between an analog and a digital signal is made by the sequencing circuit. A nonlinear converter between digital and analog signal presentation is also disclosed. Resolution of the coder/decoder is increased by providing a reference voltage generator capable of supplying stepped increments of the reference voltage to the capacitor array during the comparison process.

摘要： A fast parasitic-insensitive continuous-time filter and equalizer integrated circuit that uses an active integrator is described. Circuit techniques for excess-phase cancellation, and for setting the corner-frequency of the filter and equalizer are also described. These techniques result in a filter and equalizer chip with performance independent of process, supply, and temperature without employing phase-lock loops. This 20MHz 6th order Bessel filter and 2nd order equalizer operate from 5V, and generate only 0.24% (-52 dB) of total harmonic distortion when processing 2 Vp-p differential output signals. The device is optimized to limit high-frequency noise and to amplitude equalize the data pulses in hard disk read-channel systems. The device supports data rates of up to 36 Mbps, and is built in a 1.5.mu./4 GHz BiCMOS technology.

摘要： An algorithmic analog-to-digital and digital-to-analog converter 10 combines the techniques of switched capacitor cyclic conversion by using first and second amplifiers 31, 32 with capacitors C.sub.1, C.sub.1 ', C.sub.2, C.sub.2 ', C.sub.3, C.sub.3 ', C.sub.4, C.sub.4 ', C.sub.5, C.sub.5 ' communicating with the inputs of said amplifiers 31, 32 and between the inputs and outputs of said amplifiers 31, 32, and the techniques of reference voltage refreshing. The performance of the converter 10 is capacitor ratio-independent. Because of the ratio-independent aspect, very small component values can be used, and as a result, the die area required for the circuitry can be quite small.

摘要： A bridge circuit for a measurement bridge of the type using four impedance arms provides an output referenced to ground which is a function of the impedances in the respective arms. The bridge circuit includes an impedance bridge comprising first, second, third and fourth impedance arms connected in series loop with first, second, third and fourth bridge terminals serially defined at the connections between the respective arms. A source of constant current is connected between the first terminal and ground. A driver is connected to bridge terminals other than the output terminal. The driver is responsive to bridge terminal signals to provide a bridge output which is a function of the impedances in the respective arms.

摘要： An active filter employing a plurality of integrators which may be fabricated as a metal-oxide-semiconductor (MOS) integrated circuit is described. S-plane zeros are obtained without additional active devices when compared to prior art filters without such zeros. The zeros result from resistive coupling between the integrators. Resistance ratios and capacitance ratios primarily determine the filter's characteristics rather than the absolute value of these elements. This permits the filter to be readily fabricated with existing MOS technology.

摘要： A self calibrating algorithmic analog-to-digital converter is disclosed for which the gain of the conversion loop is precisely adjusted and controlled by an array of switched capacitors such control being stored in a latch. The offset of the gain stage is reduced by reducing the amount of charge injected from the gate of the input zeroing MOS switch.
