In this paper we design of an adaptive Nero fuzzy system with mixed-signal inputs and digital outputs. In this paper analog advantages including low die area, high speed and simplicity are added to the digital advantages, such as programmability, robust against noise and distortions. a new programmable Fuzzifier circuit based on mixed-signal input, and min circuit for inference and Multiplier/D...

This paper illustrates how analog circuitry can be used to decode turbo and turbo-like codes. For ease of exposition, the focus is on a simple two dimensional product code comprised of a 2 by 2 array of (3,2) single parity check codes. It is shown that the heart of the decoder is a soft exclusive-or operation which is easily implemented in analog as a modified Gilbert multiplier. Finally, a com...

The study of quadrant marked mesh patterns in 132-avoiding permutations was initiated by Kitaev, Remmel and Tiefenbruck. We refine several results of Kitaev, Remmel and Tiefenbruck by giving new combinatorial interpretations for the coefficients that appear in the generating functions for the distribution of quadrant marked mesh patterns in 132-avoiding permutations. In particular, we study qua...

The paper presents the concepts behind the "Urdhva Tiryagbhyam Sutra" and "Nikhilam Sutra" multiplication techniques. It then shows the architecture for a 16×16 Vedic multiplier module using Urdhva Tiryagbhyam Sutra. The paper then extends multiplication to 16×16 Vedic multiplier using "Nikhilam Sutra" technique. The 16×16 Vedic multiplier module using Urdhva Tiryagbhyam Sutra uses four 8×8 Ved...

Analog multipliers are used for frequency conversion and are critical components in modern radio frequency (RF) systems. RF systems must process analog signals with a wide dynamic range at high frequencies. A mixer converts RF power at one frequency into power at another frequency to make signal processing easier and also inexpensive. A fundamental reason for frequency conversion is to allow am...

A memristive neural network computing engine based on CMOS-compatible charge-trap transistor (CTT) is proposed in this paper. CTT devices are used as analog multipliers. Compared to digital multipliers, CTT-based analog multipliers show dramatic area and power reduction (>100x). The proposed memristive computing engine is composed of a scalable CTT multiplier array and energy efficient analog-d...

We present a new approach to the design of high-performance low-power linear filters. We use p-channel synapse transistors as analog memory cells, and mixed-signal circuits for fast low-power arithmetic. To demonstrate the effectiveness of our approach, we have built a 16-tap 7-b 200-MHz mixed-signal finite-impulse response (FIR) filter that consumes 3 mW at 3.3 V. The filter uses synapse pFETs...
