WebbIf we’re measuring at frequencies faster than that, the op-amp hasn’t had time to keep its inverting input voltage fixed. Instead, the op-amp’s output could be considered fixed, because at high frequencies, it doesn’t have time to change voltage. In this case, we’ll see Rin+Rf looking into the overall circuit’s input. http://practicingelectronics.com/articles/article-100024/article.php

This type … Webbsaturating the op amp at around ±10-15 V. The input impedance of an op amp circuit is the ratio of the applied voltage to current drawn (v in/i in). In practical circuits, the input impedance is determined by assuming that the op amp itself draws no current; any current drawn is assumed to be drawn by the remainder of the biasing and feedback ...

Webb6 jan. 2016 · In reality, an op-amp cannot supply voltages beyond its (unseen here) supply rails, and the diode would sensibly be rated to break down at a higher voltage, so the op-amp output sits near the negative rail ('saturated') and the diode is reverse biased (aka 'off') with only a bit of leakage current (some nA typically) flowing.
