Abstract
AbstractIndium phosphide (InP)‐based transistors play an important role in high‐speed circuit and high‐frequency analog circuit applications. Over the past few decades, terahertz heterojunction bipolar transistor (HBT) is increasingly developed. As a result, many reports of HBTs operating at terahertz region have flourished. Since the high‐frequency circuit design faces the challenge from the lack of precise transistor models, this paper reviews the development of high‐frequency modeling technologies of InP HBT at terahertz region. Processes in the development of small‐signal models at terahertz frequencies, precise parasitic parameters extraction method, improvements in measurement, and the de‐embedding technologies open up more opportunities for precise representation of InP HBTs. Finally, some excellent terahertz circuits based on InP HBT are reviewed.
