The present paper addresses an improved low-power high-speed buffer amplifier topology for large-size liquid crystal display applications. The proposed buffer achieves high-speed driving performance while drawing a low quiescent current during static operation. The circuit offers enhanced slewing capabilities with a limited power consumption by exploiting a slew detector which monitors the output voltage of the input differential amplifier and outputs an additional current signal providing slew-rate enhancement at the output stage. Post-layout simulations show that the proposed buffer can drive a 1 nF column line load with 8.5 V/μs slew-rate and 0.8 μs settling time, while drawing only 8 μA static current from a 3 V power supply.

Medical Equipments

Advanced medical equipments embedded with the sensors, analog to digital converters (ADC) and other equipment. Gain amplifier and the comparator are key blocks in ADCs improvement. Comparator is the key element in achieving a low offset and high slew ratein the ADCs, in addition power and speed optimizationdesigns are preferred. To achieve high speed and low power a modified architecture of a comparator is introduced. A 5V two stage comparator is designed to meet the specifications as, offset value <8.4mV, power dissipation <1.5mW and slew rate>14.68V/µS. Cadence Virtuoso tools and SCL 0.18 µm technology parameters are used for design. Designed comparator shows improved slew rate and power consumption in comparison with the existing comparators
