Low-noise tunable band-pass filter for ISM 2.4 GHZ bluetooth transceiver in ±0.7V 32 nm CNFET technology

Abstract

This paper presents a CNFET-based low-noise band-pass filter for application in 2.4 GHz Bluetooth transceivers. The proposed circuit exploits the ultrawide voltage and current bandwidths of CNFET-based analog building blocks as compared to their CMOS counterparts. Tuning of the center frequency is demonstrated via variation of a grounded resistor. SPICE simulations show that the CNFET-based building block consumes only 15% power as compared to its CMOS equivalent. Noise analysis and Monte Carlo analysis also demonstrate the high performance characteristics of the proposed circuit.
