A flipped current mirror and a flipped voltage follower suited to low-voltage and low power operation is applied to the design of current conveyors (CCII). A new topology (class-A )is proposed operating at 1.5v and featuring simplicity, compactness, low power consumption and bandwidths up to 100 MHz for a 0.5μm CMOS technology.

The challenges of mobile ad hoc network are to maintain quality of services and performance. Many routing protocols like AODV discover routes whenever required by the source node and the benefit in doing so is that no prior knowledge of the topology is required. The AODV routing protocol is commonly and effectively used for mobile, ad-hoc nodes. So far, many maintenance strategies have been proposed on AODV to provide better QoS services performances. Some has used the radio propagation characteristics of mobile nodes in ad hoc network during route maintenance. Some modification has been done on computation of delay parameter. The other modification was on multi route selection during route discovery considering only delay as QoS parameter. This paper aims towards proposing a new route maintenance strategy with multiple options that will lead to better performance during link failure on a route. During route discovery and route reply procedure two different QoS parameters considered here are delay and bandwidth. The routes should be selected during route discovery process. The route maintenance strategy may be applied to both the routes independently and simultaneously by the internal nodes where the link failure has occurred.
