Take the following circuit: The transistor turns the voltage input into a proportional current. Then it is said the resistor Rd turns the current back into a voltage. Then to calculate the output impedance of this circuit you would take Rd in parallel with the transisor's r0. But If you...
The purpose of the current mirrors (and/or current sources) is to turn on the output stage (M19 M21) to a proper extent, so as to apply the correct voltage at the load. It does so whether it needs to sink current or source current, and it automatically calculates the amount of ...
The transistor is to the positive rail. A version of this amplifier using current-source biased by MT and must maintain a rela- p-channel input transistors would similarly suffer with tively constant gate-source drive consistent with the bias respect to noise on its negative supply. In order ...

Really :-) I have never seen this... I guess any small signal transistor like BC547/2N2222 etc. will do the job(?) sw guy Title:Re: Is this opamp impedance thing? Post by:EraldoonFebruary 04, 2024, 10:15:50 am If you're going to buy diodes then just buy a couple Bav199 whi...
Further, if you already have an op-amp circuit that does what you want, except you need it to source more current, adding the transistor this way won't significantly alter the function of your circuit. If you also need to sink current: ...
Output Short Circuit Current Output short circuit current gives us the maximum current that can source or sink from the output of an opamp. In some applications opamp may needs to drive whose impedance is approximately zero (means output voltage approximately zero). ...
D2 provides a little voltage offset so the LED current starts from zero as a Miller ramp generator cant start from zero unless you have a negative bias supply. The source vReset and the .model SW are highly LTSPICE specific, to provide timed control of SW1, the integrator reset switch....
