Analog Computation in the Digital Age

چکیده

The Science Museum in South Kensington, London, was founded during Queen Victoria’s reign, and although it is imaginatively run and well worth a visit, it is scarcely renowned for its humor. But while I was in their Computer Science Area recently, I laughed so much, and so loudly, that I barely escaped arrest for disorderly behavior. The cause of my uncontrolled mirth was a glass case labeled “Obsolete Analog Computing Technology,” containing, among other things, an AD534 analog multiplier. ADI has been making this device for more than 30 years, and it continues to generate substantial sales revenue. In fact, there are a number of operations where analog processing has clear advantages over digital, and this article will discuss some of them.

Comparison of computerized digital and analog radiography for detection of bronchial pattern in dogs

Background: Analog radiography has been replaced with digital radiography for canine diagnostic imaging in many veterinary clinics. There is no data comparing these modalities in a veterinary clinical setting to detect bronchial pattern signs in dogs. Objectives: In this study, computerized digital radiography (CR) and analog radiography were compared for diagnosis of bronchial pattern in dogs....

Improving adaptive resolution of analog to digital converters using least squares mean method

This paper presents an adaptive digital resolution improvement method for extrapolating and recursive analog-to-digital converters (ADCs). The presented adaptively enhanced ADC (AE-ADC) digitally estimates the digital equivalent of the input signal by utilizing an adaptive digital filter (ADF). The least mean squares (LMS) algorithm also determines the coefficients of the ADF block. In this sch...

Comparing the Effectiveness of Digital and Analog Mammography in Breast Cancer Diagnosis and Screening: A Systematic Review and Meta-Analysis

Background & Objectives: Breast cancer is the most common cancer among women and one of the leading causes of death in the productivity ages. Mammography screening is the main method for the diagnosis of breast cancer. While analog mammography counts as the standard method of screening, the digital one can be an alternative. This review compared the effectiveness and safety of these technologie...

Optimal fast digital error correction method of pipelined analog to digital converter with DLMS algorithm

In this paper, convergence rate of digital error correction algorithm in correction of capacitor mismatch error and finite and nonlinear gain of Op-Amp has increased significantly by the use of DLMS, an evolutionary search algorithm. To this end, a 16-bit pipelined analog to digital converter was modeled. The obtained digital model is a FIR filter with 16 adjustable weights. To adjust weights o...

Designing an Integrated All-Optical Analog to Digital Converter

We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...

Analysis of Integral Nonlinearity in Radix-4 Pipelined Analog-to-Digital Converters

In this paper an analytic approach to estimate the nonlinearity of radix-4 pipelined analog-to-digital converters due to the circuit non-idealities is presented. Output voltage of each stage is modeled as sum of the ideal output voltage and non-ideal output voltage (error voltage), in which non-ideal output voltage is created by capacitor mismatch, comparator offset, input offset, and finite ga...
