My guess is this: two of the 1Meg resistors are used to set the gain. The 100k resistors are used to reference the positive input to 1/2 the supply voltage. one of the 22 nf caps is at the input, and the other bypasses the "lower" 100k resistor to ground. The 2.2uf cap is at the output. signal repeating wireless router

"WebA voltage buffer, also known as a voltage follower, or a unity gain amplifier, is an amplifier with a gain of 1. It’s one of the simplest possible op-amp circuits with closed-loop feedback. " - Gain buffer

Gain buffer

A unity gain buffer amplifier may be constructed by applying a full series negative feedback (Fig. 2) to an op-amp simply by connecting its output to its inverting input, and connecting the signal source to the non-inverting input (Fig. 3). Unity gain here implies a voltage gain of one (i.e. 0 dB), but significant current gain is expected. In this configuration, the entire output voltage (β = 1 in Fig. 2) is fe… WebFeb 17, 2024 · This unity gain buffer is only one option; others (with gain perhaps) should also be considered for their settling characteristics in delivering the stimulus waveform to the DUT. This active buffer stage is intended to provide a low impedance wideband source to the DUT – particularly useful for driving an inverting input impedance.
