“…As an example, time functions, defined by equations (12) and (14), with amplitude and frequency of an input signal of 1 V and 50 Hz, respectively, and ω 0 =100 rad/s are shown in Fig.5. As for the RMS value and output signal ripple V out (t) (upon vanishing of the transients), both functions are equivalent.…”

“…Equation (25) suggests that the filtering function, represented by the integral operators, equation (12), has different characteristics compared to the ideal situation, equation (13), especially in the operators' behavior at higher frequencies. For signals whose fundamental frequency is approximately five times the cutoff frequency of the output current to voltage converter, a much better average accuracy than 1 % will be achieved.…”

“…Although these schemes require only NPN transistors, their circuits are operated in only one quadrant and employ the full-wave rectifier. A new design technique for RMS-to-DC converter relies on the dual translinear-based squarer circuit proposed in [12,13], where the input current can be a two-quadrant current signal. Given that the full-wave rectifier is not required within this conversion scheme, the circuit exhibits a wide bandwidth, which, due to the input interference, still appears limited compared to thermal-based or diode-based detectors [14].…”

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 design technique for RMS-to-DC converter that design around a dual trans-linear-based squarer circuit is proposed in [15,16], where the input current can be a two-quadrant current signal. Because the full-wave rectifier is not required by this conversion scheme, the circuit exhibits a wide bandwidth, but limited compared to thermal-based or diode-based detectors (due to input interference) [17].…”

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.
