Abstract
A low-voltage ultra-low-power two-quadrant current squarer based-true RMS to DC converter circuit is presented in this study. The proposed current squarer is based on two translinear loops with matched NMOS transistors operating in the weak inversion region. Ultra-low-power dissipation of 1.4 nW, multi-decade frequency range of 0.5 Hz–55 kHz and large input dynamic range of 72 pA–1 nA (with error <3%) are the main achievements of the proposed design while constructed of only ten transistors. Post-layout simulations with 0.8-V supply voltage using HSPICE software in 0.18 μm TSMC CMOS process (level-49 parameters) verified the good functionality of the proposed circuit. Moreover, Monte Carlo analysis is performed to validate the satisfactory PVT robustness and reliability of the design's performance.
