A dual-channel baseband transmitter has been designed for global system for mobile communications (GSM) cellular phone application. It has been fabricated in a 0.35-μm digital CMOS process as part of a single-chip solution for baseband processing. Each channel consists of a switched-capacitor digital-to-analog converter, a switched-capacitor filter, a class-AB buffer, and an active-RC filter. The lack of on-chip precision capacitors and resistors poses a major challenge in designing these analog building blocks. Another key implementation issue is to maintain the performance of these analog circuits in the presence of substantial substrate noise from the digital signal-processing core. The current consumption is 8.8 mA, and the total active area is 5.1 mm2 . The channel response meets the Gaussian minimum-shift-keying spectral mask
