Abstract
This work presents the design and measurement results of a high-linearity differential programmable gain amplifier for VHF applications. Based on a new version of the degenerated differential pair, it is implemented in a 0.35 /spl mu/m CMOS technology and consumes 1.95 mW from a 3.3 V supply. The programmable gain varies from 0 to 16 dB in 4 dB steps through a 4-bit word. Experimental results show bandwidths over the 100 MHz range and total harmonic distortion figures below -60 dB.
