For the first time, an ultra-wideband pulse generator is fabricated in GaAs HBT IC technology. The generator includes delay and differential circuits to convert a TTL input into an impulse signal and a Class-C amplifier to increase the pulse amplitude while compressing the pulse width. By adjusting the bias of the Class-C amplifier, the pulse amplitude can… CONTINUE READING
