Summary:A very low voltage, current-mode CMOS RMS-to-DC converter is presented. It is fully designed using MOS Translinear techniques. More specifically, its main building blocks are a squarer/divider and a geometric-mean cell which are obtained by using simple second-order MOS Translinear loops in a folded configuration, leading to a very regular and compact implementation. A novel biasing technique is employed for such loops, allowing them to operate at supply voltages as low as 1.5 V. Experimental results for a prototype IC demonstrating the correct operation of the circuit are included.
