Abstract
This article presents an all-digital, crystal-less
impulse radio ultra-wideband (IR-UWB) transmitter for the
high-density neural implants with several thousand channels.
A six-order hybrid modulation scheme combining the differential
16-pulse-position modulation (D16PPM), pulsewidth modulation
(PWM), and differential bi-phase shift keying (DBPSK) is
proposed to achieve a high data rate and guarantee the
transcutaneous data transmission. A detailed theoretical analysis
of the signal-to-noise rati
