The practical design approach presented here with the examples shown not only makes solving multiple-input op-amp summer circuits simple, it actually makes them fun to solve.

The input protection resistor R1 serves a number of functions here. The first relates to circuit function, namely limiting the zener peak current at switch-on to a safe level. The remainder relate to ...

Stackpole's RMCF Series thick film general purpose chip resistors are now available in 5% tolerance design kits. The 5% kits have been added to supplement the popular 1% design kits. Each kit ...

Figure 9 An example P-Channel voltage controlled resistor circuit with a feedback resistor network R3 and R4 to lower distortion. If you will note that in Figures 8 and 9 , the feedback resistor ...

Now when you solve, you’ll get the best resistor values from the standpoint of accuracy (10 and 11.11 ohms). By changing the constraints, you could ensure you get the answer you need. Spread ‘Em ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in ...
