Abstract :
This paper presents Operational Transconductance Amplifiers (OTA) designed on a pre-diffused array of digital Sea-Of-Transistors (SOT) using trapezoidal association of transistors (TAT) to emulate a single equivalent full-custom transistor. The TAT transistor is a composite of minimum channel length transistors, that achieves a DC and AC performance comparable to its equivalent single transistor. OTA amplifiers in both full-custom and SOT array methodology were implemented to allow better performance comparisons. The experimental results obtained for 1.0 μm digital technology are presented
