Cell-based variable-gain amplifiers with accurate dB-linear characteristic in 0.18 µm CMOS technology

A simple and robust “cell-based” method is presented for the design of variable-gain amplifiers (VGAs). The proposed unit cell utilizes a unique gain compensation method and achieves accurate dB-linear characteristic across a wide tuning range with low power consumption and wide bandwidth. Several s...
