Abstract

We propose a unique wideband amplifier configuration. The new configuration adopts an improved Darlington amplifier to broaden the bandwidth and flatten the output gain. The low power consumption and matched impedances are also achieved in our amplifier. This circuit has been realized using Toshiba 0.35μm SiGe BiCMOS technology with the fT of 30GHz. The simulation result of the presented amplifier demonstrates 1-10GHz bandwidth and 11.3-dB maximum forward gain (S21) with less than ±0.5-dB gain flatness while it drains 8mA from a 3-V supply. A 1-dB compression point and an DP3 of -12.5dBm and 6dBm respectively also have been reported in this paper.
