A 2 Gb/s 1.8 pJ/bit Differential BPSK UWB-IR Transmitter Using 65 nm CMOS Technology

A differential BPSK transmitter for ultra-wideband impulse-radio communication has been presented in this paper. The transmitter, developed in a 65 nm CMOS process,is simple in design and occupies a core area of 0.0017 mm 2 . The differential Gaussian monocycle pulses (GMP) are generated using some logic blocks and delay elements. The generated GMP, having a center frequency above 5 GHz, meets the FCC regulations. Measured results show that the transmitter consumes 1.8 pJ/bit to transmit BPSK modulated GMP at a data rate of 2 Gb/s. The interface circuitries eliminate the need for external networks for chip to antenna matching. Using an off-chip differential bow-tie antenna, data can easily be transmitted up to a distance of 10 cm which made it suitable for low power far field non-coherent applications.
