Description

また、温度等の影響によって容量Ｃ0、Ｃtの値が変動する場合でも、第１、第２のコンデンサ４６、２３が、同じ材質・構造で、同じ半導体集積回路装置内に形成されている場合は、その容量変化の割合は同じであり、容量の比Ｃ0／Ｃtは変化しないので、上記(７)式を逸脱するようなことなない。
 Furthermore, even if the values of capacitances C0 and Ct fluctuate due to the influence of temperature, etc., if the first and second capacitors 46 and 23 are made of the same material and structure and are formed within the same semiconductor integrated circuit device, the rate of change in capacitance will be the same and the capacitance ratio C0 / Ct will not change, so there will be no deviation from the above equation (7).
