    Abstract

    Design of an inductor-less wideband variable-gain amplifier (VGA) using a cell-based strategy is presented. The VGA has a measured gain range of 24 dB, of which 17.3 dB is dB-linear with less than ±0.3 dB gain error. The -3 dB bandwidth is from 2 GHz to 2.2 GHz for the entire dB-linear range. An output 1 dB compression point of 1.8 dBm and a noise figure of 24 dB are measured. Due to the simple structure, the current consumption of the VGA core is only 2.9 mA from a 1.2 V supply, and the size is only 225 μm × 45 μm, excluding pads.
