Set the simulator so the – input (the inverting ... Comparing voltage divider performance with and without a 1x amplifier This circuit demonstrates the power of a 1x amplifier.

A very simple and cheap tv antenna amplifier circuit built with BF961 a N–Channel Dual Gate ... so if you don’t use it for the tv set you can receive your favorite radio stations in better conditions.

Use a power supply rated at 350 mA. The amplifier gain is dependent of the resistors R4 and R6. The values shown in the circuit gives a gain of 11. The voltage at the junction of R13 and R14 must be ...

Shown is the standard op-amp schematic symbol ... The single supply biases one input to set the output halfway between the positive supply and ground. Capacitive coupling on the input and output ...
