Abstract :
A simple CMOS squarer circuit is proposed. The circuit has a Giga Hertz frequency response that has advantages to be used in communication systems. The proposed circuit focuses on the extension to ultra wide bandwidth. The circuit is based on 0.18 mum CMOS technology simulated using PSPICE level 7. The circuit has wide dynamic range, GHz-bandwidth response and low power consumption. The proposed circuit has been simulated with SPICE and achieved -3 dB bandwidth of 10.96 GHz. The power consumption is about 86.51muW with a plusmn 1 V power supply voltage. Simulation result shows that the proposed squarer can accommodate the whole UWB bandwidth.
