“…High-frequency performances of these devices are limited to less than 5 MHz due to the band-width and the slow rate of the fullwave rectifier. Design techniques based on bipolar dynamic trans-linear circuits were proposed to implement true RMSto-DC converters [10,11]. Although these schemes require only NPN transistors, their circuits are operated in only one quadrant and employ the full-wave rectifier.…”

A current-mode bipolar power detector based on a novel synthesis of translinear loop squarer/divider is presented. The circuits consist of a single multiple-output current controlled current differencing transconductance amplifier (MO-CCCDTA), two current controlled conveyors (CCCII), and one resistor and one capacitor that are both grounded. The errors related to the signal processing and errors bound were investigated and presented in the paper. The PSpice simulation and experimental results are depicted, and agree well with the theoretical anticipation. The measurement results show that the scheme improves the accuracy of the detector to better than 0.04 % and wide operating frequency range from 50 Hz to 10 MHz. The maximum power consumption of the detector is approximately 5.80 mW, at ±1.2 V supply voltages.

A new realization of RMS detector, employing two CCCIIs (controlled current conveyors), metal-oxide-semiconductor transistors and single grounded capacitor is present in this paper, without any external resistors and components matching requirements. The proposed circuit can be applied in measuring the RMS value of periodic, band-limited signals. The proposed circuit is very appropriate to further develop into integrated circuits. The errors related to the signal processing and errors bound were investigated and provided. To verify the theoretical analysis, the circuit PSpice simulations have also been included, showing good agreement with the theory.

“…Alternate implementations of translinear circuits can be found in [4,[6][7][8]15,30,32,36] for log-domain filters, in [9,28] for RMS-to-DC converters, in [33,41,45] for oscillators, and in [40,42,45] for phase-locked loops.…”

“…While no formal comparison to alternate implementations of RMS-to-DC converters is presented here, it is worthwhile to note that the implementation detailed in Section 3.3 does not assume a rectified input signal as do most published implementations. Additional RMS-to-DC converters are published in [28] and [9]. can be expected to be fairly high considering the frequency range and the capacitive nature of the circuit (becoming increasingly worse at higher frequencies).…”
