Abstract

Electronics used in medical applications attract lots of researches on it, consequently more patients will be treated and have a healthy life. The analog-to-digital converter (ADC) is the inter-connection between the analog and digital part of a device, plays an important role transferring signals in real life to signals in digital domain. One requirement for this ADC is how to reduce power dissipation that can afford devices using battery source. A MDAC (Multiplying Digital to Analog Converter) using charge-pump capacitor technique is introduced for pipelined ADC topology. Compared with the switch-cap technique, MDAC using charge-pump technique consumes less power, hence reducing the total power used in the device. This MDAC is proposed for 1.5-bit stage pipelined ADC, using UMC 0.25μm technology, 2.5V supply and 0.5Mhz sampling rate.
