In this paper, an 8-bit envelope modulator as part of a digital polar transmitter for Bluetooth and WLAN is demonstrated. The modulator performs digital-to-analog conversion, up-mixing and power amplification, allowing for an area-efficient, fully-integrated transmitter architecture. The circuit delivers 24.8 dBm peak-power and 16.7 dBm WLAN OFDM power with… CONTINUE READING
