A 1.227 GHz low power single-ended input, differential output low noise amplifier (balun LNA) for GPS is proposed. A two stage structure with current-reused technique is adopted to achieve low power, low noise factor and high voltage gain simultaneously. The LNA is fabricated in 0.18 mm CMOS process, consuming only 2 mA current from a 1.8 V supply. The LNA is measured to exhibit a differential ...

A BiCMOS temperature stable voltage-tofrequency converter is described. The circuit includes an input voltage-to-current conversion stage followed by a voltage-controlled current switch. The switch is controlled by a nonsaturated multivibrator with a limiter of the output voltage swing. The multivibrator thresholds are stabilized using a current produced in a bandgap voltage reference. This all...
