Novel architectures of class AB CMOS mirrors with programmable gain
Two schemes for power-efficient gain-programmable V-I conversion based on class AB CMOS mirrors are introduced. The proposed topologies also allow for high-speed gain-programmable precision rectification. Experimental results from a test chip prototype in 0.5-mum CMOS technology with +/-1 V supplies are shown that validate the proposed circuits.
