A typical piezoelectric sensor comprises a disk of PZT-5A ceramic material with metallized electrodes on its surfaces. Applying electrically conductive epoxy to the electrodes connects external wiring ...

Current‐mode amplifiers have emerged as a highly efficient alternative to traditional voltage‐mode systems, particularly in high frequency and low power electronic applications. Their ability to ...

Editor’s note: Most modern designs have been using voltage mode elements like op-amps for implementation of various electronic circuits. These elements are used widely due to their small sizes and ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

Questyle’s Sigma Pro ($899) and Sigma ($599) portable DAC with headphone amplifiers offer Current Mode Amplification, Bluetooth LE, and LDAC. Previewed at CanJam London 2025, the new Questyle Sigma ...

Using a resistor and voltage amplifier across it for current sensing presents a conundrum. On one hand, it appears to be near-trivial application of Ohm’s Law via I = V/R. It certainly looks easy: A ...

The DIA2240 device is an automotive qualified high precision, bidirectional and zero-drift current sense amplifier with enhance PWN rejection. The device sense drops across the shunt resistor over a ...
