TIME CONSTANT CIRCUIT, SWITCH CIRCUIT, DC/DC CONVERTER, AND DISPLAY DEVICE |
摘要 |
To provide a time constant circuit and the like capable of acquiring a characteristic of an output voltage that attenuates gradually after attenuating steeply, compared to a characteristic that attenuates monotonously. The time constant circuit includes: a series/parallel circuit formed by serially connecting a plurality of parallel circuits each formed with a resistance element and a capacitance element between a first terminal and a second terminal; and a voltage-dividing resistance element connected between a third terminal connected to the second terminal and a fourth terminal. A first parallel circuit is formed with a first resistance element and a first capacitance element, a second parallel circuit with a second resistance element and a second capacitance element, and an n-th parallel circuit with an n-th resistance element and an n-th capacitance element. Note that “n” is the number of the parallel circuits and it is an integer of 2 or larger.
