Design and Analysis of High Speed Body Bias Control and CLSA Sense Amplifier

This paper deals with a design and analysis of current latch sense amplifier with a current-reuse technique (Body bias control sense amplifier) and conventional CLSA sense amplifier. The Body bias control sense amplifier is capable of high-speed pre-charging with little increase in power dissipation. Body bias control sense amplifier also controls body bias voltages of pre-charge transistors rather than in a conventional CLSA. Also we find that sensing time of body bias control sense amplifier is less as it depends upon threshold voltage. We also verify the various result like Slew Rate, Power consumption, Voltage Gain, Offset Voltage Sensitivity at 180 nano meter technology for both type of sense amplifier. From these result we see that when Vdd increases circuit ability to avoid the noise increases but power consumption also increases and accordingly current consumption increases. Simulation result shows that speed of Sense Amplifier decreases but interesting improvement in current consumption is obtained. Sensitivity of conventional CLSA sense amplifier is 50mV and for body bias control sense amplifier is 35 mV.
