including RC circuits and rectifiers, by using op amps and negative feedback.. ( with low frequency limit). R. –. +. RB. sources have a high output impedance?).
The input impedance of an OP-AMP is very high and probing either input with a. 10,000 to 100,000 but most OP-AMP have surrounding components that limit the . For this reason, the 1u must be a low leakage device such as a TANTALUM.

why op amps have low output impedance

"Chapter 8 - Current - Feedback Op Amp Analysis".

With their low-input currents, FET input op amps are uni- versally used in monitoring. turns to accurate conversion of the photodiode output to a linearly related. anyone who has used high resistance op amp feedback in more general.
For example, most of today's CMOS op amps have a high output impedance (in open loop).. 2. One-Stage Op Amps. - Gain too low: gm(ron II rop). Observation: Feedback can raise the output impedance of a cascode stage: Implementation.
