This paper presents a 16-bit 100MS/s SAR ADC with 1V power supply for biomedical implant systems developed low technique i.e., DTMOS logic. It consists of R-2R DAC, low-power comparator, digital logic low-leakage. The designed comparator is differential architecture that has used to have an excellent, common-mode noise rejection. Comparator was created proper operation remain in saturation and ...

..-htracf —A high-speed CMOS comparator has been designed and fabricated using a standard 3pm process. A dynamic latch preceded by an offset-cancelled amplifier is used to obtain a response time of 43 ns. The offset-cancelled amplifier reduces the input-referred offset so that medium-resolution analog-to-digital converters (ADC’S) can be built with this comparator. The use of pipefining within ...

digital part. Recently a simple comparator scheme has been The use of simple digital window comparators for the onpresented in detail. Based on digital gates in different chip evaluation ofanalogue signals is described. II is shown that configurations, a so-called digital window comparator [6, 101 can a window can be created by choosing different gate input he realised. This, paper deals with t...

This e The original application for the circuit in Figure 1 was to check the number of revolutions of an engine with only one LED as an indicator. The measurement of the number of revolutions usually involves sensors with a frequency output proportional to the number of revolutions. The circuit compares the frequency output of such a sensor with a lower and upper limit and gives a visual result...

The paper describes an improvement of the chopper method for elimination of parasitic voltages in a low resistance comparison and measurement procedure. The basic circuit diagram along with a short description of the working principle are presented and the appropriate low resistance comparator prototype was designed and realized. Preliminary examinations confirm the possibility of measuring ext...
