IBM 65nm CMOS 3-Channel 10-Bit 350Msps+ Current-Steering D/A Converter

Overview

This IP specifies a 3-channel 10-bit resolution, high performance, low power CMOS Digital-to-Analog Converter (DAC) which offers exceptional direct current and alternating current performance and supports update rates up to 350 MSPS with a power-down mode to reduce the standby power dissipation. It is fabricated in an advanced CMOS process. Segmented current source architecture is combined with a proprietary switching technique to reduce spurious components and enhance dynamic performance. Edge-triggered input latches and a temperature compensated bandgap reference have been integrated to provide a complete monolithic DAC solution.
