Abstract

We report two terahertz monolithic integrated circuit (TMIC) amplifiers operating at 500 GHz. The 6-stage single-ended power amplifiers use Teledyne's 130 nm indium-phosphide double heterojunction bipolar transistors in a common-base configuration. The impedance matching networks of the first amplifier are designed with shunted lines while the second amplifier uses shunted metal-insulator-metal capacitors. We measured and compared the small-signal and large-signal performance of the two amplifiers around 500 GHz. Although the two TMICs exhibit a similar transducer gain (24 dB) and output power (up to -0.7 dBm), we obtain a better yield with the amplifiers designed with shunted lines.
