Time Division Duplexing (TDD) Adjusted Carrier Feedthrough Evaluation
Texas InstrumentsTime Division Duplexing (TDD) is a communication technique allowing for two-way communication within the same frequency band by alternating the transmission times of a device. An important parameter for devices in these TDD-transmission systems is the transient response of the adjusted carrier feedthrough when the devices are rapidly turned on and turned off. When a device transitions to the activ

Design Considerations for DC-DC Converters in Fast-Input Slew Rate Applications
Texas InstrumentsThis application report describes the ways to optimize the design of DC-DC converters (TPS54040-Q1 TPS54060-Q1 TPS54140-Q1 TPS54160-Q1 TPS54240-Q1 TPS54260-Q1 TPS57040-Q1 TPS57060-Q1 TPS57140-Q1 and TPS57160-Q1) in applications with fast transition at the input voltage on the rising and falling edges. First the issues faced under such a scenario are analyzed. Then design considerations
Power-Up Behavior of Clocked Devices (Rev. A)
Texas InstrumentsSome logic devices, such as flip-flops and shift registers, require the use of a clock input, typically designated CLK or CP. The state of the outputs of these devices change once an appropriate clock edge has occurred. Device datasheets specify whether the action occurs on a positive or negative edge of the clock. However, the behavior of a device upon power-up is not always specified before a valid clock edge has occurred.
Adding Hysteresis to Supply Voltage Supervisor
Texas InstrumentsSome applications require supply voltage hysteresis to keep a supply voltage supervisor (SVS) from falsely resetting the system due to voltage dips and glitches. This application report presents one solution for adding hysteresis to an SVS. The solution schematic is given along with component selection criteria and equations such that readers can appropriately scale the solution to their own re
