A GaAs High Speed Driver Circuit for R.F. Switches

Abstract

This paper describes a high speed driver circuit for GaAs MMIC R.F. switches. The device can switch a 4 pF load through 10 volts in less than 2 ns. A novel output circuit optimises power consumption. The circuit has been realised on the Plessey Three-Five standard production foundry process; circuit performance agrees well with SPICE predictions.
