Silicon CMOS/SiGe transceiver circuits for THz applications

Abstract

The push towards terahertz frequencies presents both challenges and opportunities for emerging applications and circuit. In this paper, recent attempts to operate SiGe and CMOS technologies beyond their transistor cut-off frequencies will be presented. Among others, the circuit designs include monolithically integrated THz CMOS focal-plane arrays and 820 GHz sub-harmonically pumped SiGe HBT imaging chip-sets including integrated antennas.
