Balancing non-inverting opamp gain to minimize distortion

The Experiment Here is a common dual opamp configuration: U1A is an attenuator configuration while U1B is a positive gain configuration. Here R3 is just a resistor to ground, but in practice R3 might represent a sub-circuit consisting of an active filter. What is the relationship between the two opamps regarding their gain and distortion…

555 Timer cheatsheet

Here's is a quick visual guide to illustrate how the trigger and threshold pins can affect the output of this timer IC chip. Trigger active Here the signal sent to the trigger is less than 1/3 of the supply voltage (VCC). The output is 1. The discharge transistor is disabled. Threshold active Here the signal…
