1. Inverting SummationOperational Amplifier The inverting summation is relatively simple and can be understood as the superposition theorem. Uo=-(R3/R1+R3/R7+R3/R5)*2, the factor of 2 is because the negative terminal voltages are equal; if they are not equal, each needs to be multiplied accordingly. PS: I basically haven’t forgotten this. Simulation Result 2. Non-Inverting SummationOperational Amplifier The … Read more
Abstract This article presents a design scheme for a DC adjustable voltage regulator based on Multisim 14 simulation. The design includes a basic voltage regulation module, a voltage stabilization circuit, and a protection circuit, capable of providing stable output voltage under different load conditions. The performance of this power supply design in terms of voltage … Read more
The amplifier circuit can increase the output power of a signal. It obtains energy from the power supply to control the output signal waveform to be consistent with the input signal but with a larger amplitude. In this sense, the amplifier circuit can also be viewed as a controllable output power source used to achieve … Read more
