A simple approach is a cascade of a common noninverting sample-and-hold amplifier and an inverting amplifier. A classic inverting amplifier is an op amp with voltage feedback from two resistors. The ...

In some applications, a linear amplifier is required which has different gains with regard to the polarity of the input signal. Figure 1 shows an inverting amplifier which is linear within the second ...

The circuit is based upon a design from the 1990s which as far as we can see is a pretty conventional non-inverting amplifier. It has an on-board op-amp to create a virtual ground, and three ...

The schematic in Figure 1 is a common summing amplifier with multiple inputs and one single-ended output. It is a variation of a standard inverting amplifier. Point X is a virtual ground and is ...
