Abstract: A continuous time delta sigma modulator includes a quantizer, a buffer module, and a reference module. The quantizer includes a comparator that updates a digital output each cycle of a clock signal based on a comparison of a reference potential with an input generated based on a sample of an analog signal. The buffer module receives the digital output, stores the digital output for a predetermined delay period, and outputs the digital output after the predetermined delay period as a delayed digital output. The predetermined delay period is less than one cycle of the clock signal. The reference module selectively varies the reference potential based on the delayed digital output.

Abstract: A track-and-hold amplifier circuit capable of increasing hold mode isolation includes an input circuit to buffer an input signal coupled to a switching transistor. A clamping transistor couples to the base of the switching transistor, and a hold capacitor couples between the emitter of the switching transistor and circuit ground. A differential amplifier circuit has a first input for receiving a track signal and a second input for receiving a hold signal. When the differential amplifier circuit receives the track signal, the switching circuit closes to charge the hold capacitor. When the differential amplifier receives the hold signal, the switching transistor opens to store the voltage representative of the input signal on the hold capacitor and the clamping transistor clamps the voltage at the base of the switching transistor. Thus, the base emitter voltage of the switching transistor is zero volts, and the signal held by the hold capacitor is independent of the input signal.
