摘要

This paper describes configurable, 3.6 to 7.5 GHz pulse UWB transmitter IC targeted for neurological implants with high data rate requirements. Each cycle of the RF pulse is digitally programmable in amplitude and duration, enabling a very flexible shaping of the transmitted PSD signal, without the use of an output filter. The transmitter achieves a maximum of 34% of energy efficiency when drawing 8.5 pJ/bit from the supply, with 13 µW of constant static power. This transmitter was implemented in 65nm CMOS and measures 1.0 mm × 0.7 mm. A 32-channel recording experiment using this chip is also reported.
