Low Voltage, Low Power and High Performance Current Conveyors for Low Voltage Analog and Mixed Mode Signal Processing Applications

摘要

A novel CMOS current conveyor (CC), which can be reconfigured into various types of CCs and is capable of operating at ± 1.0 V, is presented. The proposed CC has near rail-to-rail input (- 1.0 to 1.0 V) swings and consumes 0.6 mW power. The input current range of the proposed CC is from -0.5 to 0.5 mA. P-Spice simulations confirm the CC performance. The CC has a voltage transfer bandwidth of 100 MHz and current transfer of bandwidth of 200 MHz. Applications of CCs in the design of square rooting and current squaring functions have also been explored.
