Abstract
This paper presents the design of a 3rd-order lowpass /spl Sigma//spl Delta/ analog-to-digital (A/D) converter using a continuous-time (CT) loopfilter. The loopfilter has been implemented by using active RC-integrators. The influence of the low supply voltage on the building blocks such as the amplifier and the common mode feedback as well as on the overall /spl Sigma//spl Delta/ modulator is discussed. Simulation results of the 1.5 V CT /spl Sigma//spl Delta/ A/D converter show a 75 dB dynamic range in a bandwidth of 25 kHz. The expected power consumption is less than 300 /spl mu/W.
