dc.description.abstractThis paper presents a new simple current-mode square-rooting circuit based on CMOS technology. The proposed circuit consists of only one CMOS operational transconductance amplifier (OTA) with source degeneration and one MOS transistor. The input signal of the circuit is a current and the output is a current proportional to the square root of the input current with high-output impedance level. OTA with source degeneration is used to provide wide input dynamic range. The circuit also exhibits wide bandwidth and good temperature stability. PSPICE simulation results are used to demonstrate the performance of the proposed square-rooting circuit.
