Current mirror ratio
Webcurrent mirror in the output side is a wide-swing cascode one, which increases the gain. The basic idea of the FC-OpAmp is to apply cascode transistors to the input differential … WebIf we consider the B-E voltage of the two transistors fixed, then the ratio of output current to input current will be R1/R2. If R2 is half of R1, for example, then the mirror will want to sink twice the current at OUT that you put in to IN.

WebIn the above equation, notice that the DC current in transistors M5,6 is K times larger than the currents in transistors M3,4. The transconductance can be set by the tail current source, current mirror ratio, or size of the input transistors. The transconductance is usually the most important parameter, and it is fortunate that WebA current mirror is a transistor circuit that regulates the current through a load resistance, the regulation point is set by a simple resistor adjustment. Transistors in a …

Vanity Table … WebA current mirror is a circuit block which functions to produce a copy of the current flowing into or out of an input terminal by replicating the current in an output terminal. An important feature of the current mirror …
WebIref = 100uA. Due to the 1:1 ratio between M3 and M2, 100uA flows through M2 and M1. Phase 2 Iref increases to 200uA. Due to the 1:1 ratio between M3 and M2, 200uA flows through M2 and M1 M1 has a bias voltage on it's gate to support only 100uA, so the drain-source voltage of M1 (=Vout) must increase to support this new 200uA current.
