Abstract :
A novel method for the active compensation of parasitic capacitances in high speed resistor string D/A converters is described. The experimental results obtained from a 10 bit DAC show that the approach proposed is essential to the achievement of a 50 MHz clock rate when using commercial 1.2 μm CMOS analog technology
