Pulse generating circuit with temperature compensation |
摘要 |
A pulse signal generating circuit includes a ring oscillator and an internal voltage generating circuit. The internal voltage generating circuit generates an internal voltage depending on an operation temperature. The internal voltage is low at a normal temperature, and is high at a high temperature. Each inverter in the ring oscillator is driven by the internal voltage supplied from the internal voltage generating circuit. Thereby, a period of a pulse signal increases at a normal temperature, and decreases at a high temperature.
