摘要

This invention provides an oscillation circuit that can reduce a short-circuiting current that flows through the inverting amplifier and oscillate with low power consumption. The first semiconductor switching element 42 and second semiconductor switching element 52 included in the inverting amplifier 30 are prevented from being on simultaneously to limit a short-circuiting current flowing through the inverting amplifier 30 when the oscillation circuit is driven. The first semiconductor switching element 42 and second semiconductor switching element 52 are connected in parallel to the constant current sources 600, 610, and a shortage of power necessary for stabilizing oscillation is offset by power from the constant current sources. <IMAGE>
