We present an ultralow-power, ultra-wideband (UWB) transmitter (TX) in standard 65-nm CMOS processes. The TX consists of feedforward edge combiners and interpolators for ultralow-power operation and reliable pulse generation that is essential in UWB TXs. The implemented circuit avoids pulse overlapping without complicated calibrations and has achieved an energy efficiency of 4.32 pJ/b at 200-Mbps data rate. The TX is suitable for energy-constraint, high-data-rate applications such as wireless telemetry in implantable high-density neural recording interfaces.
