Title:
OSCILLATION CIRCUIT
Document Type and Number:
Japanese Patent JP2014075744
Kind Code:
A
Abstract:

To provide an oscillation circuit that precisely outputs an oscillation signal of a desired frequency.

According to an embodiment, an oscillation circuit 1 is an oscillation circuit including a pulse generation section 10, and the pulse generation section 10 includes a comparator 103 for comparing a voltage Ve1 with a reference voltage Vref to output a comparison result Ve3 in a normal operation mode and setting a voltage at a non-inverting input terminal at the level of the reference voltage Vref in an initialization mode, and a comparator 104 for comparing a voltage Vf1 with the reference voltage Vref to output a comparison result Vf3 in the normal operation mode and setting a voltage at a non-inverting input terminal at the level of the reference voltage Vref in the initialization mode.
