Abstract
A new design technique for a true rms-to-dc converter is implemented around a dual translinear-based squarer circuit. A dual translinear loop and current mirrors are the basic building blocks in this realization scheme, and the computation is carried in current-mode. The conversion circuit consists of a squarer, a low-pass filter and a square-root circuit. Since no rectifier function is required, this converter configuration enables us to obtain a wide-band frequency response. The input signal can be voltage or current. In addition, the modification of the converter to construct a vector summation computing circuit is also discussed. © 1998 IEEE.
