Abstract :
This paper presents the design of a 1.5 V CMOS fully-differential inductorless RF bandpass amplifier using a 0.35 μm n-well CMOS technology. The bandpass amplifier employs a novel low-voltage floating active inductor as the tuned load. HSPICE simulation of the proposed bandpass amplifier operating at 1 GHz centre frequency and a quality factor of 50 illustrates that a 50 dB voltage gain and a 4.2 dB noise figure can be achieved with the total power dissipation of 46 mW under a 1.5 V power supply voltage
