A 5.35 mW 10 MHz Single Opamp Third Order CT Modulator With CTC Amplifier and A

This paper reports a continuous-time (CT) thirdorder delta-sigma modulator that features a single amplifier.biquad (SAB) and a passive integrator to simplify the circuit.to just one power hungry operation amplifier (opamp). Such.setup not only relaxes the gain and bandwidth requirement of.the opamp
