Triangle wave generating circuit |
摘要 |
A triangle wave generating circuit comprising: a pulse generating circuit configured to generate a plurality of pulse signals with the same period and with phases different from one another; and a plurality of charge/discharge circuits configured to be supplied with the plurality of pulse signals, respectively, the plurality of charge/discharge circuits each including: a current supply circuit configured to supply to a capacitor a first current for charging at a predetermined current value or a second current for discharging at a predetermined current value; and a charge/discharge control circuit configured to switch between the first current and the second current when the pulse signals are supplied thereto and when a voltage across the capacitor reaches a predetermined reference voltage, the first current and the second current supplied from the current supply circuit to the capacitor.
