Shunt feedback input impedance

This is an inverting Transimpedance Amplifier. The current will see a very small input impedance and here is how to prove the statement: $$I_{in} = \frac{V_{in}}{R_i} + \frac{V_{in}-V_o}{R_f}$$ $$V_o …

Explaining the positive and negative regions of the output waveform in a circuit involving a...

During (+) cycle the Zener diode is reverse biased (Vz = 5). The other 5 V will be divided on the two resistors so the voltage across R3 is around 2.5 V. During the (-) cycle the Zener diode is forwar …
