Web22 de nov. de 2024 · At the Q1 collector node, write a KCL equation (assume identical transistors): I r e f = I C 1 + I B 1 + I B 2 = I C 1 ( 1 + 2 β) Thus. I C 1 = I r e f 1 + 2 β. and it follows that. I B 2 = I B 1 = I r e f β + 2. thus (ignoring the Early effect) I C 2 = β I B 2 = I r e f β β + 2. It's straightforward from here to include the Early effect ...

Web13 Bad MOS Current Mirror Example This is not a current mirror since the relationship between VX and IREF is not clearly defined. The only way to clearly define VX with IREF is to use a diode- connected MOS since it provides square-law I-V relationship. 14 Example: Current Scaling Similar to their bipolar counterpart, MOS current mirrors can also scale … Web6 de jun. de 2016 · The MOSFET Constant-Current Source Circuit. Here is the basic MOSFET constant-current source: It’s surprisingly simple, in my opinion—two NMOS transistors and a resistor. Let’s look at how this circuit works. As you can see, the drain of Q 1 is shorted to its gate. This means that V G = V D, and thus V GD = 0 V.

A current mirror replicates the input current of a current sink or current source as an output current. The output current may be identical to the input current or can be a scaled version of it. The above current mirrors are referenced with respect to ground. Current mirrors can
Web25 de jun. de 2024 · 4. In this differential amplifier: The PNP transistor Q6 acts as an active load resistor and as a current mirror. Since current source Q6 has nearly infinite impedance, we will be able to have very large voltage gain Rc/r'e in which Q6 is the Rc. However, intuitively speaking, I don't get how this current source will generate large gain.
