WebSep 14, 2024 · The sensitivity to dc magnetic field is studied under different ac excitation field and dc bias field. We found that the highest sensitivity is 17.6 V/Oe at zero bias … WebFinally, the phenomenological model predictions of material property changes under DC bias electric field and compressive stress were compared with experimental data reported by our group. The proposed model succeeded to explain the material properties change under external biases. Furthermore, the effect of DC electric field and compressive ... how can environmental damage be minimised

Also, to investigate the loss mechanisms, the three losses (dielectric, elastic and piezoelectric losses) were determined under low and high power conditions. Mechanical loss tan φ’ displayed a change WebMar 24, 2010 · The bias is the operating point. For a bipolar transistor (BJT) the bias resistor will maintain enough current into the base so that the transistor is neither saturated (fully on) or cut-off (fully off). Some BJTs come with an internal bias resistor to reduce the parts count in a design. If you are switching BJTs on or off you don't need a ... how can enzyme activity be inhibited
