Improve frequency response of current mirror
http://soc.hanyang.ac.kr/eng/conference/international/fulltext(6).pdf Witrynaconventional current mirrors is rather high input impedance, while especially in current mode signal processing the node impedances have to be very small. In fact this impedance has a substantial effect on overall dynamic range and frequency response of the circuit. 2. Conventional Current Mirror
