Hello, my friends,
Recently, I want to design a low-power voltage-controlled voltage source circuit. I googled a circuit (figure below) to realize this, however, I do not understand the functions of C1 and Q1 clearly. Why do not let node 1 as the output node? The circuit is from this website: Voltage Controlled Voltage Source - Daycounter
I attach the LTSpice simulation file for your help. Thanks a lot!
