  • PCB Layout Guidelines for High Voltage Amplifiers
    As circuit size shrinks it may not be practical for today's high voltage amplifiers to adhere to the old PCB trace spacing design rules of yesteryear. As far back as 1980, Sandia National Laboratories did a study* to determine new trace spacing rules that would be reliable. Sandia found
  • AN-16 PCB Layout Guidelines for High Voltage Amplifiers
    Standard company design rules for printed circuit boards may not meet the requirements for high voltage amplifiers manufactured by Power Amp Design. The article proposes PCB geometries consistent with successful field applications for high voltage amplifiers.
  • Avago Technologies: Automotive Isolation Amplifier for Voltage Sensing (.pdf)
    The introduction of electric and hybrid electric vehicles have added high voltage electric modules into the car. The battery stack in a hybrid can be in excess of 150V, higher for the inverter driving the motor
  • Operational Amplifier Topologies and DC Specifications
    . The current or voltage excitation to the sensor, quite often is generated by an amplifier circuit. Following the front end sensor circuitry, an op amp is used to implement a low pass, band pass or high pass filter. In this portion of the circuit, gain stages are also implemented using programmable
  • How to Control the Interference of Transformer to Amplifier?
    be effectively avoided, so that the amplifier can be obtained. Excellent sound. In addition to powering the amplifier, the power transformer can also couple the amplifier to the power supply, so that the interference source in the power grid enters the amplifier, and also reflects the voltage
  • How to Monitor Sensor Health with Instrumentation Amplifiers
    By their very nature, in amps are a good choice to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp instrumentation amplifier architecture performs this function with the input stage providing a high input impedance while the output stage
  • Some Tips on Making a FETching Discrete Amplifier
    Low-noise amplifiers for photodiode, piezoelectric, and other instrumentation applications typically call for circuit parameters such as extremely high input impedance, low 1/f noise, or subpicoamp bias currents that cannot be met with available integrated products. This article discusses
  • M540: GaAs MMIC Low Noise Amplifiers (SOIC-8 Platform)
    Early in 1994, M/A-COM began offering a family of plastic packaged GaAs MMIC low noise amplifiers (LNAs) featuring single positive supply voltage, low noise figure, high dynamic range, and low power consumption for the high volume commercial wireless communications market. These MMIC LNAs use M
