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-...

Implantable image sensors have several biomedical applications due to their miniature size, light weight, and low power consumption achieved through sub-micron standard CMOS (Complementary Metal Oxide Semiconductor) technologies. The main applications are in specific cell labeling, neural activity detection, and biomedical imaging. In this paper the recent research studies on implantable CMOS i...

In this paper we present a low power scan design method. Nowadays the Boundary Scan (BS) diagnostic access to the circuit input and output cells combined with a scan chain of concatenated internal flip-flops (FF) has become to be a standard. An alternative parallel diagnostic access method called Random Access Scan (RAS) is not used in nowadays ICs because of more difficult routability. In spit...

A low power consumption AMF (Analog Matched Filter) is proposed which utilizes capacitor Multiply and capacitor Accumulation operations. High speed high precision A/D converter is unnecessary because the proposed circuit directly samples received analog signal. The code shifting MF structure is used to prevent error from accumulating. A 15-tap AMF circuit was fabricated using CMOS process. Powe...

New military communications require increased versatility for the transmission of a wide range of data, voice and images. There are many algorithms needed for communication like FFT (Fast Fourier Transform), DCT (Discrete Cosine Transforms), Viterbi coders and decoders, trellis techniques etc. Advances in VLSI technology continue to improve the quality of algorithm that can be implemented on a ...
