“…The current‐mode RMS‐to‐DC converters circuits that operate in weak inversion regions [1, 9–11, 36, 37, 48], usually suffering from low bandwidth, low input dynamic range and low linearity, but also featuring certain major advantages such as low supply voltage and power dissipation. In contrast, the other group in which transistors are biased in the strong inversion region [6, 7, 26, 41, 46, 47], achieves a wider input range, lower distortion and linearity error, while at the same time demanding larger consumed power and supply voltage, therefore being unsuitable for low‐voltage low‐power (LV–LP) applications.…”

The study presents two new realisations of bipolar two-quadrant implicit RMS-to-DC converter and four-quadrant multiplier/divider employing two VDTAs (voltage differential transconductance amplifier) and grounded passive elements. The converters provide the operating frequency of up to 10 MHz with increased precision in the processing of input currents signals, when compared to known realisations. Errors related to the signal processing and errors bound were investigated and presented in this study. The results obtained from the simulation tests in HSPICE and the experimentally realised models of the converters showed a good match with the theoretical anticipation. The maximum power consumption of the converters is 2.82 mW, at ±1.2 V supply voltages.
