Abstract :
A fully integrated GaInP/GaAs HBT IC process with Schottky diodes, nichrome resistors, MIM capacitors and air-bridge inductors is presented. The HBTs have an fT and fmax of 60 and 45 GHz, respectively. Unloaded ECL gate delays of 28 ps are obtained from ring oscillator measurements. A divide-by-eight prescaler circuit clocks at 12.5 GHz.
