Abstract
This paper describes a bandpass amplifier topology for the GHz range using Q-enhancing that allows a systematic design approach to be used to control linearity, noise and power consumption. Frequency selectivity is achieved by a negative feedback network using an LC tank and a positive feedback network using a resistor to achieve Q-enhancing. The feedback networks are fully passive in order to minimize noise and distortion.
