Abstract

This work presents gain interpolating variable gain amplifier (VGA) design aspects. A technique is introduced to improve the VGA input handling capability from a few hundred millivolts to rail-to-rail without affecting any other performance parameters and with low complexity. An additional technique is proven by hand analysis and simulations to reduce the 3rd order intermodulation products (IM3) of the VGA by 4dB. The VGA is designed in an IBM 0.13μm BiCMOS 7LM technology. It has a 56.5dB gain control range and draws 1.76mA from a 3V supply.
