Terahertz detector and method based on N×M dielectric resonant antenna array

摘要

The present disclosure discloses a terahertz detector based on a N×M dielectric resonant antenna array, wherein a N×M on-chip dielectric resonant terahertz antenna array is connected to a matching network, the matching network is connected to a source of a NMOSFET, a gate of the NMOSFET is sequentially connected to a first bias resistor and a first bias voltage, a third transmission line is connected between the first bias resistor and the gate, a drain of the NMOSFET is connected to a first DC blocking capacitor, the other end of the first DC blocking capacitor is connected to a low noise preamplifier, a second bias resistor and a second bias voltage are further connected between the first DC blocking capacitor and the low noise preamplifier, and the low noise preamplifier is further provided with a voltage feedback loop. The present disclosure also discloses a design method for the same.
