Abstract
A low voltage supply CMOS current conveyor circuit for digital input signals from 0.25 V up to 1.2 V is presented. The circuit is optimized and pre-layout simulated in a 65 nm CMOS process technology. At the target design voltage of 1.2 V, the current conveyor has a propagation delay
of 2.86 ns, an energy consumption of only 80.9 pJ, and energy-delay product (EDP) of 231 pJns for resistive load of 10 kΩ. Superior performance of this work is demonstrated through comparison with other similar published work at a frequency of 5 MHz. It is shown that the proposed circuit
is suitable for digital signaling. The developed CMOS circuit perfoms correctly until 50 MHz and its EDP is 31 pJns at 10 kΩ.
