An ultra low power neuromorphic bandpass filter (BPF) for dedicated short range communication system is proposed. The filter is designed for an intermediate frequency receiver for a passband of 75 MHz with 37.5 MHz center frequency. In an effort to improve the filter performance without compromising power consumption; a standard Rm-C BPF structure is incorporated within the modified Izhikevich neuron to design the neuromorphic bandpass filter. Implemented in 45 nm CMOS technology, the proposed bandpass filter consumes 100.8 nW at a supply voltage of 0.5 V. The neuromorphic bandpass filter demonstrates excellent figure-of-merit (FOM) of -181.5 dB for a spurious free dynamic range of 27.1 dBm.
