An Energy Efficient 1 Gb/s, 6-to-10 GHz CMOS IR-UWB Transmitter and Receiver With Embedded On-Chip Antenna

— We report a high data rate (upto 1 Gbps) Ultra-wideband (UWB) transceiver for very low power applications. The transmitter side, including pulse generator (PG), power amplifier (PA) and on-chip antenna, consumes only 7 pJ/b (3 pJ/b w/o PA). The novel UWB on-chip antenna has relatively low loss of 10 dBi and allows for a more compact overall system suitable for area constrained implantable and sensor node applications. The receive side includes an active band-select filter (ABSF) and an ultra wideband low-noise amplifier (LNA). The ABSF has more than 3.9 GHz bandwidth with less than 3 dB insertion loss. The low-voltage LNA consumes 2.56 mW and achieves a minimum noise figure of 3.35 dB with 10 dB power gain and an IIP3 better than-6.8 dBm. The total area of transmitter is 0.62 x 0.48 mm 2 and receive side covers an area of 1.9 x 0.94 mm 2. The system is implemented in IBM 0.13 µm standard CMOS process.
