Abstract
A hybrid sigma-delta converter that includes a continuous-time circuit that processes an input signal and generates a first output signal, an interface circuit that receives the first output signal from the continuous-time circuit and filters the first output signal thereby generating a second output signal, and a discrete-time circuit that processes the second output signal received from the interface circuit. The interface circuit further reduces the coupling of noise generated from the operation of the discrete time circuit to the preceding continuous-time circuit.
