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) environments.

An optical input/output interface system for a Josephson junction integrated circuit is fabricated and tested. The system consists of a superconducting optical detector, a dc powered Josephson circuit ...

To solve the problem, I designed a flexible digital-interface circuit around a MAX7301 I/O expander from Maxim Integrated Products and a programmable linear-power supply comprising a MAX1658 ...

All modern high speed ADCs need an input common mode voltage for their differential inputs that must fall within some acceptable range for correct operation. This is sometimes a trivial issue where ...

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 ...

The complete interface circuit is shown in Figure 3. Figure 3: The input interface circuit. The operational amplifier U1A serves as a voltage follower, with very high input impedance and very low ...

Recently, Tianjin Jiazi Robotics Technology Co., Ltd. announced that it has obtained a patent titled "A Polymorphic IO ...

The buffer isolates the analog interface circuits from the internal switched-capacitor sampling operation. This presents the ADC driver with a controlled input impedance with greatly reduced ...

Cable and xDSL modems are experiencing increasing popularity. For this reason, many designs are now required to interface with existing telephones at the subscriber's location ...
