  • Abstract
    This paper reports on a polar transmitter that is capable of 8-DPSK modulation for the Bluetooth EDR standard. It implements the second-order approximation scheme in the gain calculation of the DCO and a phase rotation-constant digital PA. It achieves DEVM of 6.1% at 0dBm output in sending 8-DPSK signal for Bluetooth EDR, drawing 35mA from a 1.2V supply and occupies 0.75χ0.75mm2.
