| Abstract: | 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- m CMOS technology with ±1 V supplies are shown that validate the proposed circuits. |
