摘要

A low-power IEEE 802.15.4z high-rate PHY (HRP) compatible coherent transmitter is described. The proposed transmitter uses a digital polar architecture with fixed amplitude steps in the power amplifier and asynchronous time-discrete pulse shaping. The pulse-shaping unit consists of a finite-impulse response (FIR) filter using current-starved inverter-based delay taps that can be calibrated on-chip...
