With the increase in personal electronic devices, HiFi audio is more popular than ever in many applications, such as smartphones, music players, home theaters, and even car infotainment. Many engineers...

Push-Button Circuit

This push-button circuit can be used with a wide variety of PMICs. For example, this circuit can be used to drive a control pin, which enables and disables the buck...

Designing With The HMC346MS8G Voltage Variable Attenuator

The HMC346MS8G is an absorptive Voltage Variable Attenuator (VVA) in an 8 lead surface-mount package operating from DC - 8 GHz. It features an on-chip reference attenuator for use with...

Design and Implementation of a Bias Sequencing Circuit for the HMC463LP5 Low Noise Amplifier

The HMC463LP5 is a GaAs MMIC PHEMT Low Noise AGC Distributed Amplifier packaged in a leadless 5 x 5 mm surface mount package which operates between 2 and 20 GHz...

Short-to-Battery Protection Strategies for Class-D Amplifiers

With class-D amplifiers, short-circuit faults in the output H-bridge result in dangerous current paths. This type of fault occurs when either the positive or negative outputs (OUTP or OUTN, respectively)...

ELM327 Circuit Construction

When constructing an electronic circuit, it is often best to build it in stages, testing each as you proceed. The following pages provide typical voltages that you might expect as...

Design and Application Guide of Bootstrap Circuit for High-Voltage Gate-Drive IC

The purpose of this paper is to demonstrate a systematic approach to design high-performance bootstrap gate drive circuits for high-frequency, high-power, and high-efficiency switching applications using a power MOSFET and...

Microcontroller-Based Serial Port Interface (SPI®) Boot Circuit

This application note describes the operation of a general- purpose, microcontroller-based Serial Port Interface (SPI) boot circuit. This is a low cost solution for users who need to modify some...

Cell Phone Base Station Circuit Protection

Mobile phone base stations are often placed in exposed elevated locations for the maximum possible broadcast coverage. Often this unintentionally results in the erection of an ideally positioned lightning conductor...

Linear Circuit Devices for Applications in Battery Powered Wireless Systems

Conventional wisdom says smaller is better where battery operated wireless systems are concerned. Higher silicon integration and smaller package technology have shrunk system electronics to the point where system size...
