Abstract

This paper presents a fully integrated ultra-wideband impulse radio transmitter front-end (TFE) that is compliant with the European spectral mask. The compliance is achieved by means of 4-bit digital pulse shaping and an integrated matching network. The center frequency of the TFE is digitally tunable with 24 MHz resolution between 6.5-8.0 GHz. The TFE delivers at least 2.0 pJ pulses over the whole frequency range and achieves 4.4 % efficiency at 7.5 GHz center frequency and 4 MHz pulse repetition rate. The static power consumption is 480 nW, which enables the TFE to reach high efficiency levels even at low pulse repetition rates. The TFE is designed in a commercial 65-nm CMOS process. The performance of the TFE is evaluated through post-layout simulations.
