Small-Signal Darlington pair amplifiers with MOS-BJT-MOS hybrid unit under triple transistor topology are demonstrated using PSpice and GPDK 180nm technology in Cadence Virtuoso and Spectre tool. The first circuit under Cadence tool produces moderate voltage gain (5.156), high current gain (2165.6), wide bandwidth (15.8866 GHz), high power gain (40.4789 dB-Watt), low power consumption (556.556 mW) with low THD (11.85E-6 %) and could be used in Radar, TV and wireless communication receivers where as the second circuit with PSpice user defined model generates high voltage gain (933.235), very high current gain (44207), wide bandwidth (16.275 MHz), high power gain (76.1548 dB-Watt), low power consumption (71.6mW) and low THD (1.18%), thus it may be used in AM radio broadcast, marine and aeronautical communications. Respective amplifiers are compared with previously announced commercial transistor-based circuit which shows very promising result in terms of voltage gain, current gain, and power consumption. Proposed amplifiers are also physically verified in the Cadence using virtuoso layout editor tool which shows that it covers a small area of 80.0124 μm2 with a dimension of 8.97μm x 8. 92μm. Small-signal AC analysis, different configurations of the proposed amplifier, variation of the voltage gain with respect to different circuit components are amongst the few studies attempted in the present paper.
