Abstract :
This paper describes an IR-UWB OOK transmitter with multi-pulses per bit for bio-signal detectors which can be transplanted into the living body. The proposed IR-UWB OOK transmitter is implemented in 110 nm CMOS process where 1.33 mm2 proto-type accomplishes a maximum pulse rate of 250 Mbps while consuming 11 mW from 1 V supply voltage. It consists of impulse generator, LC oscillator, delay cell and pulse shaping filter. The output pulse centering at 3.8 GHz provides multi-pulses per bit with 210 mVpp and 44 pJ/pulse with 0.65 GHz bandwidth. Pulses are repeated in every 4 nsec irrespectively of data rates.
