Summary:
This paper proposes a new CMOS squaring circuit using voltage/current input. It consists of a mixed signal circuit and a basic squarer. Its major advantages over the other square are: this design can take two inputs (voltage input, current input), its output can be the square of a voltage signal or the square of a current signal. Simulation results are carried by PSpice program. They find that the circuit can operate at +-2_V power supplies, the voltage input range is +-0.6_V , the current input range is +-0.6 μA, the current output range is 0.55 μA and the -3 dB bandwidth is 31 MHz.
