Abstract:
An analog-to-digital converter for producing a digital representation of an analog signal, the analog-to-digital converter comprising the following:a first transconveyance amplifier having an first input terminal and a first output terminal, the first input terminal being coupled to a first input signal source; a second transconveyance amplifier having an first input terminal and a first output terminal, the first input terminal being coupled to a second input signal source; a decision circuit having a first input terminal and an output terminal and configured to convert an analog signal appearing on the first input terminal of the decision circuit to a digital value that is asserted at the output terminal of the decision circuit; a first intermediate capacitor having a first terminal and a second terminal, the first terminal being coupled to the first output terminal of the first transconveyance amplifier; and a second intermediate capacitor having a first terminal and a second terminal, the first terminal being coupled to the second terminal of the first intermediate capacitor and coupled to the first input terminal of the decision circuit, and the second terminal being coupled to the first output terminal of the second transconveyance amplifier.
