Abstract

High performance analog circuits have been realised on a purely digital Sea-of-Gates Array: an 8 bit weighted current DA-converter (typical INL of 0.2 LSB) and a class AB Opamp that has a quiescent supply current of only 23 μA, and that can drive 3.4 V_pp into a 1 kΩ load with a THD<0.1% (5 V supply). Dedicated CAD tools have been developed for a fast and reliable layout of the analog circuitry on the SOG array
