Abstract:

Systems and methods are disclosed herein to provide analog-to-digital interface techniques. For example, in accordance with an embodiment of the present invention, an integrated circuit includes an offset cancellation circuit provides offset cancellation for input signal paths under control of at least a first clock signal. A comparator, coupled to the offset cancellation circuit, provides an output signal based on a comparison of input signals provided on the input signal paths. A register receives the output signal and provides the output signal to a digital circuit under control of a first control signal, wherein the at least first clock signal is synchronized to a clock signal of the digital circuit.
