Abstract :
Conventional CMOS current mirrors with large current ratios require very large active areas and have limited bandwidths. It is shown that replacing the inefficient large ratio current mirrors with a cascade of smaller current mirrors can give significant increases in bandwidth and reductions in active area. A simple design strategy is presented which can be used to obtain near optimal tradeoffs between active area and bandwidth.
