Current mirror working
WebFrom the above equation, ‘VA’ is the Early voltage. So, the current mirror’s o/p resistance can be written as. Ro = VA/IC2. Lastly, the BJTs should be in active mode to work the … 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 …
