Abstract
A 10 bit 200 MS/s CMOS current-steering digital-to-analogue converter (DAC) employing a new voltage limiter to reduce the feedthrough of the control signals is presented. For high-speed operation of the limiter, a design technique based on the parasitic capacitor of a PMOS transistor is proposed. At 200 MS/s, a spurious-free dynamic range of 65 dBc for a 40 MHz output signal has been achieved from the proposed DAC.
