0.8-V 1.4-nW multi-decade frequency range true RMS to DC converter based on two-quadrant current squarer circuit

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, mu...

Zusammenfassung:	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
