ABSTRACT:
A peak level indicator using a field effect transistor having a semiconductive substrate with a current path portion, first and second semiconductive regions forming a PN junction therebetween, the first region being capacitively coupled to the current path portion to form a capacitor, and a rectified input signal being applied to the second region. The peak level indicator is provided with a level meter indicating a current through the current path portion.
