OTA amplifiers design on digital sea-of-transistors array

This paper presents measurement results of OTA (Operational Transconductance Amplifiers) designed in 1.0 /spl mu/m CMOS digital technology implemented in two different methodologies: in a fixed-size transistors array and in a full-custom design. Some characteristic parameters of OTA'S are compared with HSPICE simulations.
