RF Sampling 4-GSPS ADC Reference Design with 8-GHz DC-Coupled Differential Amplifier
TIDA-00431: Wideband radio frequency (RF) receivers allow greatly increased flexibility in radio designs. The wide instantaneous bandwidth allows flexible tuning without changing hardware and the ability to capture multiple channels at widely separated frequencies. This reference design describes a wideband RF receiver utilizing a 4-GSPS analog-to-digital converter (ADC), with an 8-GHz, DC-coupled, fully differential amplifier front end. The amplifier front end provides signal gain and allows capture of signals down to DC, which is not possible with a balun-coupled input.
32-bit ARM® Cortex™-M4F MCU based Small form factor Serial-to-Ethernet Converter
TIDA-00226: Serial communications have been widely used in grid infrastructure equipments. But the limitation of transmission distance and bandwidth of serial communication leads to demand for a more flexible and high-speed method to meet modern smart grid network migration. Ethernet has been accepted as an efficient communications method across industries in the last decade. This design demonstrates bi-directional switching and transmission between serial ports and Ethernet ports, which can enable legacy equipment that has only serial communication in their power grid to communicate with modern, Ethernet-based equipment without any changes to the existing hardware or software.

Inductive Linear Position Sensing Booster Pack Reference Design
TIDA-00460: Typical implementations of distance measurements use expensive rare-earth magnets. To lower overall system cost, this reference design walks through the implementation of industry’s first inductance-to-digital converters from TI for linear position sensing without the use of any expensive rare-earth magnets. Linear position sensing determines the position of a target that moves laterally across an inductive sensor that is generating a magnetic field. An inductance-to-digital converter (LDC), like the LDC1000 or LDC1101, senses inductance changes of an inductor that comes into proximity with a conductive target, such as a piece of metal. The LDC measures this inductance shift to provide information about the position of a conductive target over a sensor coil. The inductance shift is caused by eddy currents generated in the target due to the magnetic field of the sensor. These eddy currents generate a secondary magnetic field that opposes the sensor field, causing a shift in the observed inductance.
