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.

基于VDTA的新型电流模式RMS-DC转换器和四象限乘法器/除法器

这项研究提出了两个新的双极性两象限隐式RMS-DC转换器和四象限乘法器/除法器的实现，其中采用了两个VDTA（电压差动跨导放大器）和接地的无源元件。与已知的实现方式相比，该转换器可提供高达10 MHz的工作频率，并在输入电流信号的处理中具有更高的精度。与信号处理有关的错误和界限错误被研究并在本研究中提出。从HSPICE中的模拟测试和转换器的实验实现模型获得的结果与理论预期非常吻合。在±1.2 V的电源电压下，转换器的最大功耗为2.82 mW。
