摘要：
This paper presents the analysis and the design of a fully-differential digital programmable gain amplifier ( PGA) in a 0.13 mu m BiCMOS technology. The PGA has a gain control range of 31 dB with 1 dB gain step size and consumes 284mW from a 3.6V power supply. At a maximum gain of 25 dB, the PGA exhibits a 3-dB bandwidth of 10.1 GHz. The measured gain error for all 32 possible gain settings is between -0.19/ +0.46 dB at 1 GHz. Up to 13 GHz the third harmonic distortion HD3 stays below -34 dB for all 32 gain settings at a differential output peak-to-peak voltage of 1V after the last amplifier stage.
