Low supply voltage high-performance CMOS current mirror with low input and output voltage requirements
This paper presents a scheme for the efficient implementation of a low supply voltage continuous-time high-performance CMOS current mirror with low input and output voltage requirements. This circuit combines a shunt input feedback and a regulated cascode output to achieve low input resistance and very high output resistance. This scheme has a simulated bandwidth of 40 MHz and has been experimentally verified, obtaining 0.15 V input-output voltage requirements, 250 /spl Omega/ input resistance, greater than 200 M/spl Omega/ (G/spl Omega/ ideally) output resistance with a 1 V supply in a standard CMOS technology.
