Abstract— The comparator is a combinational logic circuit that plays an important role in the design of analog to digital converter. One of its most important properties is its input referred offset. When mismatches are present in a dynamic comparator, due to internal positive feedback and transient response, it is always challenging to analytically predict the input-referred random offset voltages since the operating points of transistors are time varying. To overcome the offset effect a novel time-domain bulk-tuned offset cancellation method is applied to a low power dynamic comparator. Using this comparator in analog to digital converter it does not increase the power consumption, but at the same time the delay is reduced and the speed is increased. The comparator is designed using the 250-nm CMOS technology in mentor graphics tool. Operating at a supply voltage of 5v and clock frequency 100MHZ, the comparator together with the offset cancellation circuitry dissipates 335.49nW of power and dissipates 1.027uW of power for comparator without offset cancellation circuit. The simulation result indicates that the offset cancellation circuitry consumes negligible power and it does not draw any static current. Using this high precision offset cancelled comparator in the analog to digital converter circuit the static power consumption is less and it is able to work under very low supply voltage.

Abstract— WiMAX relay networks make resource allocation decisions once per frame. An IEEE 802.16j frame consists of a downlink sub frame and an uplink sub frame. This study focuses on the downlink multicast problems. The downlink sub frame can be divided into an access zone and a relay zone. In the access zone, the BS transmits the video data to its served RSs and SSs. In the relay zone, the RSs further relay the video data to their served SSs. To determine the data transmissions within each frame, the BS should make a scheduling decision at the beginning of each frame using an appropriate resource allocation scheme. WiMAX is generally used to reduce the delays and packet loss. It a wireless standard designed to provide data transfer. In this paper mainly focuses on implementing BGWA based algorithm in order to avoid unwanted intrusion occurrences in handoff time. The Mobile Motion Prediction algorithm generally keeps track of the positions of the mobile stations and their relevant connections. The task of motion prediction is to track the motion of the mobile station in different gateways. Then different prediction methods are applied according to the sensitivity of the range to gain high precision. CAC Approach can be used to the worldwide interoperability for microwave access (WiMAX) is a promising technology for last-mile Internet access, particularly in the areas where wired infrastructures are not available. Mainly this approach is used to transmitting the video/Audio sending from base station to relay station with transmitting or secretes code.
