WebA voltage shunt feedback is a shunt-derived, shunt-fed feedback connection. Here, a fraction of the output voltage is supplied in parallel with the in put voltage through the feedback network. The feedback signal If is proportional to the output voltage Vo. This type of amplifier is called a trans-resistance amplifier. DESIGN: WebDec 22, 2016 · High linearity is obtained through complementary derivative superposition and active shunt feedback. Implemented in 130-nm CMOS technology, the prototype exhibits a -3 dB bandwidth of 2.2 GHz. In high linearity mode, the LNA achieves a minimum NF of 2 dB, a voltage gain of 21.1 dB and an I I P 3 of +14.3 dBm, with 7 mW of power consumption.
