The circuit is simple enough: it uses a capacitor, a resistor, and a pair of diodes (one of them a zener diode). He uses this basic circuit to drive simple regulators with input and output filter ...

I tested various diodes: Zener, silicon PN, Schottky barrier and LEDs, and none of these have such a sharp knee, low leakage and can carry as much current or are as flexible in use as the above ...

This circuit will clamp the voltage to a maximum of Vz, helpful when you’re feeding a signal into an analog input. This voltage clamping circuit can be used in some interesting applications.

The zener diode works withthe PCI clamp diode and the internalpulldown resistor to set the voltage levelat the input pin. To set the static level at the input pin,you must enable the FPGA’s ...

TVS Diodes in Hot-Swap Systems To prevent damage to vulnerable downstream components under these conditions, a fast response, unidirectional TVS (Transient Voltage Suppression) silicon diode [4 ...

2. Typical voltage-clamping protection circuit showing distortion due to diode junction capacitance (20-dBu output). Dotted trace is the measurement floor, i.e. diodes removed.
