摘要: Abstract A novel current-mode rms-to-dc converter architecture is introduced in this paper. It constructed from a current squaring stage and lowpass filter with low cutoff frequency realized using the concept of Log-Domain filtering. Due to employment current-splitter, two-quadrant operation capability achieved by converter. The technique offers benefits large-signal realization required time-constant capacitor an integrable value. Another attractive feature proposed scheme its low-power originated MOS transistors operated subthreshold region simple circuitry.
