چکیده
Voltage clamps for protecting low-voltage DC circuits require a new approach to circuit design. Many clamps commonly used were built for systems of 5-Volts or higher but lower voltage systems require distinctive clamping abilities. The use very low-voltage precision enhancement-mode MOSFETs play a pivotal role in designing voltage clamps in low-voltage
