Oscillating circuit |
| 摘要 |
An electric potential of an epitaxial layer 2A provided under a bonding pad 5 to which a resonance circuit for a VCO is to be connected is fixed to a predetermined (Vcc) electric potential through a resistor 6 in a conventional floating state. Consequently, a speed of a change in the electric potential of the epitaxial layer 2A is increased and a value of a parasitic capacity is stabilized quickly. Consequently, a drift can be improved when a power supply is turned ON.
