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.

Shunt based Ground Fault Protection for Inverters Powered from 220Vac Supply Reference Design
TIDA-00442: The TIDA-00442 TI design provides a reference solution for detecting ground fault in inverter based drives. Inverter current is measured on both DC positive and DC negative bus using shunt resistors. Current on DC positive bus is measured using INA170 which is powered by low side switched buck converter. Current on DC negative bus is sensed using precision opamp’s. The difference between the two measured currents is compared against a fixed threshold to determine the ground fault condition using high speed comparators.

Last Gasp Hold Up Energy Storage Solution
TIDA-00304: This solution stores and delivers "last gasp" energy for systems, such as SSDs, that require functionality for a short time after power loss in order to shut down in a controlled fashion. By storing holdup energy at higher than bus voltage the amount of capacitance can be reduced by up to 80%, significantly reducing solution size and cost while improving reliability. Typically a complex electronics circuit is needed to boost the input voltage, mux it with the buck input during power failure, and bucking it down to 3.3V or 5V for the load. This reference design uses TI’s TPS25942 on the input side to control inrush, protect against over voltage, under voltage, short circuits, and prevent stored energy from flowing back to a shorted input bus. The boost converter charges the capacitor bank to 12V if input supply is 5V, or 18V if input supply is 12V. When the TPS25942 detects and declares a fault the FLTb signal is used to drive a P-MOSFET that connects the storage capacitors to the buck input.
