High frequency analog circuit design using QuickChip

Abstract

The author describes analog circuit design methodologies and techniques required to optimize high frequency performance when operating near the upper frequency limit of BJT-based analog ASICs. The Tektronix QuickChip 2S ASIC array is used as the analysis and test vehicle. These techniques are illustrated using a series of examples including an actively shunt-peaked wideband amplifier and a multi-chip FM receiver as well as an analysis of the need to optimize the RC product in the manual routing of both metallizations in critical areas of the circuit.<>
