In this paper, a fully dual-rail input signaling structure is adopted for the APDL family, even though it increases the number of the transistors in the original circuit. HSPICE simulation shows that DAPDL shift register dissipates 6 times lesser energy than its static CMOS counterpart.","PeriodicalId":403026,"journal":{"name":"Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems.

The primary focus of this paper is on a lossless compression scheme, which incorporates three novel ideas: a simple two-step predictive structure, a simple pixel-by-pixel adaptation scheme that guarantees stability of the predictive coder, and a simple contextual entropy coder for the residuals. Also, some of these ideas are modified and extended to derive a lossy compression scheme. Experimental studies indicate that despite its overall simplicity, the proposed coder delivers significantly better compression than conventional DPCM techniques.","PeriodicalId":403026,"journal":{"name":"Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems.

This paper presents an exact closed form expression of the filter gain for a given set of filter coefficients. Based on this expression the characteristics of NPRM cost function are discussed. The selection of the initial value of the filter gain for suboptimal design methods is considered. Deficiency of the previously proposed methods is pointed out and a way to overcome the problem is presented. Proposed solution provides additional information that has been proved to be useful in determining the initial point when using a suboptimal optimization method.","PeriodicalId":403026,"journal":{"name":"Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems.

Most of the circuits work in the MOS sub-threshold region of operation to achieve very low power consumption. Supply voltage was set at 2.8 V As examples of neural networks, feed-forward and feed-back neural networks capable of recognizing black and white patterns were simulated using a transistor level circuit simulator Static power dissipation of the proposed neuron was estimated to be approximately 180 pW for the dendrite and 56 pW for the soma. In the dynamic mode, energy consumption was estimated to be 5.1 pJ (dendrite) and 1.2 pJ (soma) per activation. An analog HDL simulator was also used to simulate neural network behavior for the larger neural network examples.","PeriodicalId":403026,"journal":{"name":"Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems.
