Suppression of microwave high-speed circuit noise by using a 10 GHz transimpedance amplifier at 30 c

الملخص EN

A 10 GHz low noise Tran's impedance amplifier (TIA) is designed in which a new high-speed Angelo transistor model was employed.

Thermal circuit components were simulated for noise measurement at 30ºC at which a typical microwave noise of 20 Pa / √Hz was applied as the TIA input.

A form of feedback topology helped to reduce the minimum noise figure to 3 dB, while the |S21| parameter gain proved to be 21.7 dB.

A noise voltage at the TIA output was 3.23 x 10-15 V2/Hz.

The designed circuit showed a stability factor value of0.36 which is considered as conditionally stable.
