Abstract :
A BiCMOS current cell and current switch used in a current steering DAC are proposed. The BiCMOS self-calibrated current cell offers higher output resistance and smaller minimum voltage and shows up to a factor of 2 improvement in accuracy in simulations. The BiCMOS current switch has no base current error and achieves close to a factor of 2 improvement in simulated switching speed when compared to a MOS switch
