Schottky diode
The Schottky diode (named after the German physicist Walter H. Schottky), also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action. The cat's-whisker detectors used in the early days of wireless and metal rectifiers used in early power applications can be considered primitive Schottky diodes.
When sufficient forward voltage is applied, a current flows in the forward direction
A typical Schottky diode, on the other hand, might have an on state voltage of . A doubler using this Schottky diode will result in a voltage of , or at the output after the smoothing diode, .
Switched capacitor circuits Cross-coupled switched capacitors.
Cross-coupled switched capacitor circuits come into their own for very low input voltages. Wireless battery driven equipment such as pagers, bluetooth devices and the like may require a single-cell battery to continue to supply power when it has discharged to under a volt
