Disclosed is an op-amp circuit with current-controlled hysteresis that is insensitive to PVT variations. In the circuit, a digital output signal is output from an output buffer based on the output voltage at an output node of an op-amp. A current source is connected to the input side of ...

Figure 1. The op amp with its noise sources and input capacitance. Total op amp noise (ignoring RF thermal noise) is INOISE= in+ 2πfCINen(added rms-wise). By virtue of feedback, the minus input is fixed at virtual ground so the current noise in passes directly through RFan...
Re: Current measurement IC ( Op Amp ) for hight voltage versus Max Supply voltage « Reply #3 on: August 17, 2020, 09:19:00 am » Op amps have a rated common mode voltage, so for example if your shunt resistor is placed for high side current sensing, voltage on one point ...
It is shown that there exists non-ideal currents in op-amp power-supply leads which were formerly considered to be zero. These currents become very large at high frequencies and introduce the main source of errors in these circuits. The equations of the non-ideal currents are given in the ...

A small change to the standard current mirror op amp configuration is shown to improve performance, with few, if any, disadvantages. Adding a pair of fixed current sources allows reduced operating-point current in the output stage, while the resulting leveraging effect increases slew rate. For eq...
