A current-mode true RMS-DC converter using translinear principle based on a novel synthesis of a current squarer/divider circuit and a low pass filter circuit is presented. The circuit employs CMOS transistors operating in saturation region and the implicit computation method is designed. They find that a wide input dynamic range (50 μA), low supply voltage (1.2 V), low power consumption (1.25 nW), and low relative error less than 1%. Simulation results by HSPICE show high performance of the circuit and confirm the validity of the proposed technique.
