摘要：
An all-digital out-phasing transmitter suitable for software-defined radio (SDR) is presented. It uses a phase-locked loop followed by two digital phase rotator blocks embedded in two delay-locked loops. The chip is fabricated in a 90nm CMOS process with total active area of 3mm(2). and tested for GSM and WCDMA standards. The whole transmitter excluding phase-to-digital converter (PDC) consumes 55mA, and current consumption of the PDC is 70mA.
