摘要：
A new realization of root mean square (RMS) detector comprising two controlled current conveyors, metal-oxide-semiconductor transistors and a single grounded capacitor is presented in this paper, without any external resistors and components matching requirements added. The proposed circuit can be used for measuring the RMS value of periodic, band-limited signals. Inherently, the circuit is well suited for IC implementation. The errors related to 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. The maximum power consumption of the converter is similar to 4.28 mW, at +/- 1.25 V supply voltages.
