Abstract: This paper describes the design of a current-mode, active-passive second-order, continuous-time Sigma-Delta Modulator(ΣΔM).

Abstract: This paper describes the design of a current-mode, active-passive second-order, continuous-time Sigma-Delta Modulator(ΣΔM).

The proposed ΣΔM uses a single continuous-time current-mode integrator combined with low-pass passive filter topology to obtain the best compromise between ...

In this paper, passive continuous-time (CT) Sigma Delta modulators are briefly reviewed and compared with conventional active CT Sigma Delta modulators.

A fifth-order CT Sigma Delta modulator with a hybrid active-passive loop filter is realized with only three active integrators, robust to the excess loop delay.

This second-order modulator is composed of a passive SC integrator and a proposed hybrid passive-active integrator. The following sections discuss the main ...

as the advantage that being passive it doesn't require a biasing current and with high resistances it consumes little power as well. The common mode signal goes ...

A continuous-time (CT) sigma-delta (ΣΔ) modulator clocked at 128 MHz with a hybrid active-passive loop filter is presented for WCDMA applications.
