CMOS 8-Bit Binary Type Current-Steering DAC

A CMOS 8-bit binary type current steering Digital to Analog Converter DAC with dynamic random return to zero technique to improve dynamic performance is presented in this paper. Current steering DAC has advantage of constant output impedance and high conversion rate. To demonstrate the proposed technique, 8 bit CMOS DAC is designed and layout is prepared in 90 nm technology. Computation of Integral Non Linearity (INL) and Differential Non Linearity (DNL) performance parameter is done. Chip layout consumes 57 mW power and 5483 (µm)2 are
