“…Explicit computation techniques use a cascade of squaring, averaging, and then square-rooting circuits, computing the RMS value directly according to (1) [2]. However, the one quadrant implementations require a full-wave rectifier at the input [2]. Depending upon the type circuits used, both of these schemes can be one or two quadrant implementations.…”

However, implicit computation schemes use indirect methods to perform the conversion.…”

In this paper, systematic implementation of current-mode RMS-to-DC converters based upon MOS translinear (MTL) principle, utilizing symmetric cascoded MTL cell (SCMC) is proposed. Theory of operation and mathematical analysis of both explicit (direct) and implicit (indirect) techniques for realization of SCMC-based RMS-to-DC converters are discussed. The SCMC includes a folded MTL loop and realizes an MTL equation. MTL principle utilizes the square law characteristics of saturated MOS transistors to realize square-root domain (SRD) functions. The SCMC is constructed by two connected cascoded current mirrors and has a compact, symmetric, and multi-purpose structure, with capability of implementing the circuits into the programmable and configurable structures. The proposed RMS-to-DC converters utilize the SCMC along with a configurable current mirror array. The required squaring and square-rooting functions are realized using the SCMC, after proper configuration of the current mirror array. The proposed circuits have been implemented using a reconfigurable architecture fabricated in a 0.5 μm CMOS technology.

“…It is extensively employed to compute the AC power of electronic equipment and systems such as biomedical, communication and instrumentation ones [1][2][3]. RMS-to-DC converter circuits have been implemented in bipolar technology [4][5][6][7][8] and modern CMOS technology [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Current-mode design/processing holds further benefits than voltage-mode one, comprising wider bandwidth, higher linearity, lower power consumption, lower supply voltage and complexity [26,27].…”

“…Depending on the computation method, current-mode RMS-to-DC converters can be grouped into explicit (direct) [16,19,22] and implicit (indirect) [11, 13-15, 17, 18, 20, 22-25] types. The explicit computation technique shown in Fig.…”
