摘要： PURPOSE:To reduce the number of elements required for obtaining desired voltage value by using one channel electrode as the node of a FET for converting a level and a capacitor, ON-OFF signals as a gate electrode and the other channel as output. CONSTITUTION:Voltage boosted by the first boosting circuit 1 is applied to a circuit block 2, and the capacitor 32 is charged at polarity shown in the figure. Accordingly, a -phi singal is shifted to potential higher by 4V and reaches a -phi1 signal in the gate signals of an FET 25, the FETS 25, 26 are alternately at ON- OFF by the -phi signal and the -phi1 signal, and a phi2 signal is formed. An inverter 38 forms a -phi2 signal, and the phi2, -phi2 signals reach 5V, and are applied to the second boosting circuit 3.

摘要： PURPOSE:To convert a temperature measuring circuit into an MOSIC and at the same time to realize an automatic control of the temperature, by using a digital circuit to compensate the temperature slope or the variance of the absolute value of the temperature information signal given from a temperature-sensitive oscillator. CONSTITUTION:The time interval of the temperature measurement is set by a timer provided at a control part 6 in a temperature measuring circuit 4. The numerical values A and B are set to a gate signal counter 8 and a comparing counter 9 respectively at a moment to measure the temperature. Then the signal of a cycle setting a temperature-sensitive oscillator 7 as a signal source is fed to the counter 8; while a signal PX of a frequency fC given from a frequency dividing circuit 2 using a quartz oscillator 1 as a signal source is fed to the counter 9. In addition, the counter 9 is controlled by a control part 6 so that it starts counting at the state of the count contents B and works for the same period as the counter 8. The counter 9 stops its working when it counts A units of the gate signal. Then the value that remains finally at the counter 9 is equal to the temperature information T and transferred to a temperature register 10.

摘要： PURPOSE:To convert an integrated circuit for quartz oscillation to low electric power, by using a stable Si oxide piled substance deposited by chemical vapor deposition, as a dielectric substance placed between electrodes of capacity for resonance, in a quartz oscillator in a high frequency quartz clock. CONSTITUTION:A substrate 21 consists of an n type semiconductor whose impurity density is thin, and a semiconductor area 22 shows an area of the same type as a substrate whose impurity density is high, for taking electric contact of the substrate 21 and the surface wiring. In this case, an oxidized film 23 is an insulator consisting of a stable Si oxide piled substance deposited by chemical vapor deposition. Also, electrodes 24, 25 consist of Al, etc., and capacity for resonance formed on the semiconductor substrate through the oxidized film is capable of extremely reducing a resistance component for leading a loss in case of oscillation. In this way, it is possible to reduce electric power of the integrated circuit for quartz oscillation.
