operational amplifier
If you want the function "integrator" over some decades (6), then one can use a schematic like this (with some good op-amp) with a high feedback resistor. The feedback resistor fixes the "DC" gain (with the other resistor, 80 db) which would be "lower" than the open-loop gain (~ 120 db).
How do I decide what capacitor to use in a circuit?
I am using a voltage regulator, and to get cleaner power, the datasheet recommends using a 0.33uF capacitor. However, it doesn''t say what type it wants. Stupidly, I went out and bought a 10 pack of 0.33uF 50V Radial Electrolytic Capacitors.After looking up on this site, I found that the symbol means that it is a unpolarized capitator. ...
