This article presents a compact crystal-less impulse radio ultra-wideband (IR-UWB) transceiver designed for free-moving subjects with high-density neural implants. A six-order hybrid modulation scheme, combining differential 16-pulse-position modulation (D16PPM) and four-pulsewidth modulation (4PWM)...
