    摘要: A circuit containing a parallel connection of a first sub-circuit and a second sub-circuit is provided. The first sub-circuit comprises a serial connection of a first field effect transistor having a first threshold voltage and a first voltage dividing device. The second sub-circuit comprises a serial connection of a second field effect transistor having a second threshold voltage, which is different from the first threshold voltage, and a second voltage dividing device. The voltage between the first field effect transistor and the first voltage dividing device is compared with the voltage between the second field effect transistor and the second voltage dividing device so that a signal may be generated at a temperature at which the ratio of a performance parameter such as on-current between the first and second field effect transistors crosses over a predefined value. The signal may be advantageously employed to actively control circuit characteristics.

    摘要: An integrated circuit that includes at least one tunneling device voltage detection circuit for generating a trigger flag signal. The tunneling device voltage detection circuit includes first and second voltage dividers receiving a supply voltage and having corresponding respective first and second internal node output voltages. The first and second voltage dividers are configured so the first output voltage is linear relative to the supply voltage and so that the second output voltage is nonlinear relative to the supply voltage. As the supply voltage ramps up, the profiles of the first and second output voltage cross at a particular voltage. An operational amplifier circuit senses when the first and second output voltages become equal and, in response thereto, outputs a trigger signal that indicates that the supply voltage has reached a certain level.

    摘要: A variable digital delay line with an insertion delay as low as a single delay element yet capable of providing a large programmable delay with a small simple control mechanism. A loop connects an input to an output through selectable first delay elements such as 2:1 muxes and selectable second delay elements such as pairs of inverters by way of a plurality of intermediate nodes having a tap. A plurality of sneak paths are available wherein the loop by passes a remainder of first delay elements and/or second delay elements by way of the taps at the intermediate nodes.

    摘要: A circuit and method are provided wherein a receiver receives an input train of pulses. The circuit includes a delay-locked-loop coupled to an output of the receiver. The delay-locked-loop includes a pulse generator responsive to received input train of pulses produced at the output of the receiver for producing first pulses in response to the leading edges of the received input train of pulses and second pulses in response to the trailing edges of received input train of pulses. The leading edge of the first pulse has the same edge type as the leading edge of the second pulse (i.e., the leading edge of the first pulse and the leading edge of the second pulse are either both rising edge types or both falling edges types). The first pulses and the second pulses are combined into a composite input signal comprising the first and second pulses with the leading edge of the first pulse maintaining the same edge type. The delay-locked-loop also includes a variable delay line fed by the composite input signal for producing a composite output train of pulses comprising both the first train of pulses and the second train of pulses after a selected time delay provided by the delay line. The delay-locked-loop is responsive to one of the first train of pulses and the second train of pulses in the composite output train of pulses for selecting the time delay of the variable delay line so as to produce the composite output train of pulses with a predetermined phase relationship to the input train of pulses.
