Design issues for translating a DC coupled unipolar input to a differential ADC at some V cm. It is a challenging task to provide an ADC interface circuit to satisfy both the source and the ADC when ...
Abstract: This paper presents a programmable input/output interface circuit for some types of field programmable gate array (FPGA) devices which may be used in relatively high voltage (e.g. 5.5V) ...
Op amps are often used as drivers for ADCs to provide the gain and level-shifting required for the input signal to match the input range of the ADC. An op amp may be required because of the ...
Abstract: In piezoelectric energy harvesting, a synchronous charge extraction (SECE) interface circuit can be used to improve power conversion efficiency. Previous studies usually use additional ...
The analog input of an Espressif ESP32 doesn't seem very reactive in the very first part of its allowed range, with a lack of response, and a non-linearity in the whole range, consequently. The aim of ...
This project demonstrates how to interface a simple keyboard with the STM32F407 microcontroller using 4 push buttons as input keys and 4 LEDs as output indicators. When a button is pressed, the ...
The Linux USB input subsystem is a single, harmonized way to manage all input devices. This is a relatively new approach for Linux, with the system being partly incorporated in kernel version 2.4 and ...
