Voltage Amplifier Circuit. An common emitter amplifier circuit has a load resistance rl of 1 2kω and a supply voltage of 12v. Calculate the maximum collector current ic flowing through the load resistor when the transistor is switched fully on saturation assume vce 0.
An operational amplifier often op amp or opamp is a dc coupled high gain electronic voltage amplifier with a differential input and usually a single ended output. High voltage high side floating current sensing circuit using current output current sense amplifier low drift low side bidirectional current sensing circuit with integrated precision gain resistors. A voltage amplifier circuit is a circuit that amplifies the input voltage to a higher voltage.
So for example if we input 1v into the circuit we can get 10v as output if we set the circuit for a gain of 10.
An common emitter amplifier circuit has a load resistance rl of 1 2kω and a supply voltage of 12v. In order to achieve high voltage amplification the voltage amplifier circuit must fulfill following requirement. Voltage amplifiers many times are built with op amp circuits. An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device.
