The following is Part 1 of a four-part series. The basic one-op-amp differential amplifier consists of one op-amp and four resistors. Yet few have contemplated the depth of its complexity. It is ...
Amplifier circuit offsets are always an important topic for any amplifier design. Most voltage amplifier circuit offsets are a result of the amplifier’s input voltage offset, input bias current and ...
In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
