Abstract
One of the largest SDM DR is achieved at low power consumption by means of several SC design solutions, like multi-bit topology, large OSR, improved switching scheme, chopper & NMOS input pair, accurate opamp design. In a 3.3V 0.35μm CMOS technology, 128dB-DR in a 250Hz bandwidth is achieved with 0.75mA current from a single 2.4mW supply for high-performance instrumentation application. © 2012 IEEE.
