GPS, Part 2: Implementation
Part 1 of this FAQ looked at the basic principles of the GPS system. Part 2 looks at some hardware circuitry used to implement a GPS receiver as well as the unappreciated role that Einstein’s Theory of Special Relativity plays in providing an accurate GPS. Q What are the key elements of a GPS receiver? […]
Precision op amp sports input voltage noise of just 12 nV/√Hz, extended voltage operating range
The STMicroelectronics TSB712A precision op amp maintains stable parameters over wide voltage and temperature ranges, bringing cost-effective high-end performance to a multitude of applications, including industrial and automotive systems. Fully specified over a wide supply-voltage range of 2.7V-36V, or ±1.35V to ±18V, the TSB712A is a flexible go-to device for multiple designs that not only simplifies engineering […]
Analog switch vs. digital switch ICs
Analog switch integrated chips (ICs), when turned on, will conduct both analog and digital signals from the input pin to the output pin. Digital switches can only accept digital signals and duplicate the logic level on the input pin at the output pin. When the digital switch is turned off, it returns to a default […]
Low-leakage ESD clamping diodes protect sensors, IoT devices
New miniature (0201-size) single-line ESD-protection diodes from STMicroelectronics quickly clamp transients to a voltage as low as 7V, and handle 7A peak pulse current, to provide superior protection and design flexibility for space-constrained smart objects. This diode drops the bar with the lowest clamping voltage available at this level of capacitance and stand-off voltage. The […]
