Low-voltage wideband compact CMOS variable gain amplifier

A novel low-voltage wideband CMOS variable gain amplifier (VGA) is proposed. Using a 0.13 µm CMOS technology, the VGA exhibits a linear-dB controllable gain range of 40 dB with a bandwidth in excess of 130 MHz, while drawing only 50 µA from a single 1 V power supply voltage.
