WebJul 17, 2024 · FVF application in design of analog circuits low voltage current mirrors reported in literature can be found in [18,19,20,21,22,23,24,25,26,27,28]. In this paper, a FVF based current mirror design is proposed which has wide bandwidth with very low input impedance and extremely high output impedance. 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 …
