A mixed-signal paradigm is presented for high-resolution parallel innerproduct computation in very high dimensions, suitable for efficient implementation of kernels in image processing. At the core of the externally digital architecture is a high-density, low-power analog array performing binary-binary partial matrix-vector multiplication. Full digital resolution is maintained even with low-res...

This paper provides a tutorial overview of some recently developed methods for enhancing the accuracy and linearity of data converters (analog-todigital as well as digital-to-analog) by introducing auxiliary digital circuitry which calibrates, cancels and/or corrects the errors introduced by the unavoidable inaccuracy of the analog components used in the conversion. Simple but practical example...

Accuracy of oversampled analog-to-digital (A/D) conversion, the dependence of accuracy on the sampling interval and on the bit rate are characteristics fundamental to A/D conversion but not completely understood. These characteristics are studied in this paper for oversampled A/D conversion of band-limited signals in ( ). We show that the digital sequence obtained in the process of oversampled ...

Principles and possibilities for design and implementation of parallel analog to digital converters for application in ternary CMOS digital systems are considered and proposed in the paper. Such converters perform signal conversion from analog to ternary digital signal in CMOS ternary digital systems. First, general principle and structure for implementation and design of CMOS parallel analog t...

Nowadays, the development of the IC technology resulted in a growth of digital systems. Thus, Analog to Digital converters have become important. The important criteria of an ADC are resolution, speed and power. Among them, speed plays an important role to be enabling faster and more reliable for data processing. This paper describes a successive approximation ADC that uses a charge-redistribut...

A new architecture is presented for a single-chip tuner for digital terrestrial television, based on existing double conversion and direct conversion topologies. The new design forms part of a mixed-signal Digital Video Broadcasting–Terrestrial (DVB-T) receiver system, employing digital signal processing at baseband to ensure minimal performance requirements for the analog circuitry. To evaluat...

In many wireless applications, it is necessary to demodulate and digitize frequency or phase modulated signals. Most commonly, this is done using separate frequency discrimination and analog-to-digital (A/D) conversion. In low-cost IC technologies, such as CMOS, precise analog frequency discrimination is not practical, so the A/D conversion is usually performed in quadrature or at a nonzero int...
