This simulation demonstrates the difference between an amplifier and a comparator using an operational amplifier. In the amplifier configuration, the feedback resistor is connected to the inverting input, providing negative feedback, which stabilizes the circuit and ensures the op-amp produces a faithful, linear amplified version of the input signal without distortion. The output waveform (green) clearly shows the sinusoidal input signal amplified in proportion to the gain set by the resistor ra

Summing Amplifier: A summing amplifier is an op-amp configuration that adds multiple input voltages together to produce a single output voltage. Typically implemented using the inverting op-amp setup, each input voltage is connected through a resistor to the inverting input, while the non-inverting input is grounded. The output is proportional to the negative weighted sum of the inputs, depending on the resistor values. It is widely used in audio mixers and signal processing applications. #ampli
