IPC: H03J7/06
Filed: 1988-12-06
Abstract: PURPOSE:To attain the changeover of keyed AFC and a mean value AFC by deciding the presence of a key pulse so as to switch a cut-off frequency of a low pass filter when an FM demodulation output is smoothed and inputting the key pulse to a clock terminal of a D latch. CONSTITUTION:With no key pulse is inputted, the cut-off frequency of low pass filters 6, 13 is lowered, an AC component of an output signal of an FM demodulator 3 is smoothed and a DC component is extracted. Since the DC component is a mean value of a video signal being an FM modulation signal and the voltage and a reference voltage are compared by comparators 8, 9 to apply mean value AFC. Since a frequency error detection data for automatic frequency control circuit (AFC) is updated for each key pulse, the AFC is a keyed AFC system by adjusting minutely a local oscillation frequency by a PLL frequency synthesizer circuit so that the intermediate frequency in the key pulse period is within a prescribed frequency error. Thus, the AFC system is switched automatically.

Abstract: PURPOSE:To prevent generation of short-circuit and breakdown between a control gate and an erase gate through a double-layer structure by forming a polycrystalline silicon film, which is previously doped with phosphorus in a high concentration, to a polycrystalline silicon film forming an erase gate. CONSTITUTION:A polycrystalline silicon film 206a is formed in the double-layer structure by previously doping phosphorus in the high concentration into a polycrystalline silicon film 206 without implanting arsenic ions thereto.

In the same manner, a protrusion is not formed at the edge portion of the erase gates 207 and 207a and the fear of giving a damage on the insulating film 209 of this area can also be eliminated. In addition, damage on the area where the erase gates 207 and 207a of the insulating film 205 and the floating gate 204 are overlapped can also be prevented.
