摘要
The present disclosure discloses a dielectric resonant antenna based NMOSFET terahertz detector, comprising an on-chip dielectric resonant terahertz antenna, wherein the on-chip dielectric resonant terahertz antenna is connected to a matching network, the matching network is connected to a source of an NMOSFET, and 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 connected in parallel 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.
