The advancement in the integrated circuit design has developed the demand for low voltage portable analog devices in the market. This demand has increased the requirement of the low-power RF transceiver. A low-power phase lock loop (PLL) is always desirable to fulfill the need for a low power RF transceiver. This paper deals with the designing of the low power transconductance- capacitance (Gm-...

The need for fast power estimation methods is a growing requirement in tools which perform power consumption optimization. This paper addresses the requirement by presenting a technique which is capable of providing a power estimate using only the word-level statistics of signals within an arithmetic hardware design. By abstracting away from the low-level details of a design it is possible to r...

In this paper, we present an efficient downlink resource allocation algorithm with rate requirement consideration in multicarrier-based cognitive radio (CR) networks. The algorithm is divided into two steps aiming to maximize the downlink capacity of the network under the total power, the interference introduced to the primary users (PUs) and the transmission rate of the secondary users (SUs) c...
