1. A self-substrate-bias circuit device for use with a pulse generator comprising:
- a semiconductor substrate of a given conductivity type;
a capacitor element of MOS construction formed in said semiconductor substrate having a first side connected to the output terminal of the pulse generator;
a first diode formed in said semiconductor substrate and connected between the other side of said capacitor element and a reference potential; and
a region of said conductivity type formed in a portion of said semiconductor substrate which is contacted to and surrounding said capacitor element and having higher impurity concentration than that of said semiconductor substrate so that carriers from said capacitor element recombine with carriers existing in said region.
