Possibility of THz detection with resonant tunneling super regenerative detectors based on extremely high order harmonics

Abstract

Abstract:A super regenerative detector employing a resonant tunneling diode (RTD) was investigated for THz wave detection. A key is to use extremely high order harmonics of the fundamental oscillation of the regenerative oscillator. This has various advantages, such as circuit simplicity, easy design, and low power consumption. The basic operation and the possibility of the THz wave detection were demonstrated by circuit simulation.
