The reference current source is created using the current mirror circuit. Transconductance amplifier, whose input is some voltage and output is current. Characteristics of … If two different voltage signals are applied to the two input terminals of the op-amp, the resulting output signal is proportional to the “difference” between the two signals. Some op-amps are even specifically designed to be used as such and don’t require external circuitry. It has high common mode rejection ratio. Current amplifier, whose input is some current and output is also current but amplified. A linear amplifier like an op amp has many different applications. Differential inputs have two input pins per channel and amplify the difference in voltage between the pins. Differential amplifiers can be made using one opamp or two opamps. Amplifiers digital bookworms — you can get in a good read without spending a dime. What is an operational amplifier (op-amp)? Differential amplifiers can be easily made with a single op-amp.
