A 20Mb/s, 2.76 pJ/b UWB impulse radio TX with 11.7% efficiency in 130 nm CMOS

An UWB impulse radio transmitter for ultra-low energy neural recording applications is proposed. The transmitter is designed for robust and efficient operation in the 7.25-8.5GHz band, supporting communication ranges in excess to 4m. Powered by a low-voltage 0.5V supply, prototypes in a 130 nm CMOS technology are able to transmit 2.76 pJ/b PPM-modulated pulses to the antenna at a 20Mb/s data rate with an outstanding 11.7% overall energy efficiency.
