IP개요 This IP presents an on-off keying (OOK) driven impulse radio ultra-wideband (IR-UWB) pulse generator (PG) for 3–5 GHz applications, featuring high sidelobe suppression (SLS), large bandwidth (BW−10dB), and robustness against process variations. To eliminate the need for a dedicated offchip pulse-shaping filter, a transistor-sizing-based pulse shaping scheme is adopted to generate a broadband pulse with a triangular envelope, ensuring enhanced SLS with extended signal bandwidth. The proposed process compensating circuit mitigates the effects of process variations on the propagation delay of the logic gates to provide stable pulse timing characteristics. Implemented in 65-nm CMOS process, the prototype PG provides a UWB pulse with an amplitude of 634 mVpp, BW−10dB
of 1.12 GHz, and 27 dB SLS.
