Silicon pezoresitive-bridge pressure transducer (SPPT) is very popular in medical, industrial, environmental, and automotive pressure sensor application. The general architecture of SPPT uses a thin micromachined silicon diaphragm incorporates a implanted piezoresitive Wheatson-bridge strain-gauge. The transducer design allows only a small diaphragm deflection sin it has limited elasticity, and this produces only a very [...]

Photovoltaic transducers has been widely used in medical, consumer, scientific instrumentation, and industrial applications. Photovoltaic sensors is a solid-state devices and available for wide range of wavelength response, cover from infrared, visible, and ultraviolet spectrum. This characteristic make this type of transducer applicable in diverse jobs such as colorimetry, chemical spectral analysis, non-contact thermometry, non-invasive [...]

A DC-to-DC step-up converter is traditionally implemented using transformer, working by converting the DC voltage to AC Voltage, step-up it using transformer, then rectify and filter the transformer’s output to  get a higher DC voltage. Using a switching method, we can step-up a voltage without a transformer. We just need an inductor which is driven [...]
