| چکیده | ||
| This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its best operation. The designed LVR circuit would supply needed bias voltages. This mixer is called UWB and the changes in its necessary bias voltages would result in its weak operation. The design has been implemented in TSMC 0.18µm CMOS technology and simulated by Advanced Design System (ADS) software. Simulation results indicate good operation of regulator and mixer output during input changes. | ||
