This paper describes a 1.2-V, 12-bit, 200-MSample/s current-steering CMOS digital-to-analog (D/A) converter for wireless-communication terminals. To our knowledge, the supply voltage of this converter is the lowest for high-speed applications. To overcome increasing device mismatch in low-voltage operation, we propose an H-shaped, 3-dimensional structure for reducing influence of voltage drops (IR drops) along power supplies. This technique relaxes mismatch requirements and allows use of small devices with small parasitics. By using this technique, a low-voltage, high-speed D/A converter was realized. The converter was implemented in a 90-nm CMOS technology. The modulator achieves the intrinsic accuracy of 12 bits and a spurious-free dynamic range (SFDR) above 55 dB over a 100-MHz bandwidth.
