Abstract :
A 200 GHz CMOS amplifier with a compact fully differential configuration is presented. Accurate device modelling and creative circuit design indicate the amplifier can support gain at frequencies close to device fT. Measurement results are reported and validate the design by achieving 8.1 dB gain at 200 GHz and over 20 GHz positive gain bandwidth.
