Programmable nonlinear ADC: an illustrative example Programmable nonlinear analog-to-digital conversion is a new topic in EE curricula. With a view to introducing the EE student to the concept of transfer characteristic programmability of an analog-to-digital converter (ADC), a memory-prefetch programmable nonlinear ADC is presented. The design, analytical evaluation, and experimental implementation for the ADC are described.

The One

In this paper, a novel architecture for self-timed analog-to-digital conversion is presented and designed using the NULL Convention Logic (NCL) paradigm. This analog-to-digital converter (ADC) employs successive approximation and a one-hot encoded masking technique to digitize analog signals. The architecture scales readily to any given resolution by utilizing the one-hot encoded scheme to permit identical logical components for each bit of resolution. The four-bit configuration of the proposed design has been implemented and assessed via simulation in 0.18-μm CMOS technology. Furthermore, the ADC may be interfaced with either synchronous or four-phase asynchronous digital systems.

AbstractRethinking analog to digital conversion has become extremely crucial in the race towards aggressively scaled technology nodes with decaying signal swings. The concept of more recent TDCs, which are completely designed in digital domain, make them simpler, easier to manufacture and faster to market. In previous work, LUCOS

The main results of the development of a precision low-current meter based on a nonlinear ADC are presented. It is shown that the application of the method of nonlinear analog-to-digital conversion and a controlled voltage level at the non-inverting input of an integrating operational amplifier allows both high sensitivity and a wide dynamic range with a small spread of output codes. The use of the laboratory sample of the meter for cyclic tensile testing of steel specimens is described.

This paper presents a systematization and a comparison of the binary successive approximation (SA) variants. Three different variants are distinguished and all of them are applied in the analog-to-digital conversion. Regardless of an analog-to-digital converter circuit solution, the adoption of the specific SA variant imposes a particular character of the conversion process and related parameters. One of them is the ability to direct conversion of non-removeable physical quantities such as time intervals. Referencing to this aspect a general systematization of the variants and a name for each of them is proposed. In addition, the article raises the issues related to the complexity of implementation and energy consumption for each of the discussed binary SA variants.
