More Information
Summary:A circuit is disclosed that includes a first differential input pair, a second differential input pair, a first switch, and a second switch. The first differential input pair receives an output voltage at an output node and a first temperature-dependent voltage. The second differential input pair receives the output voltage and a second temperature-dependent voltage. When the output voltage reaches the second temperature-dependent voltage, the first switch is turned on to pull up the output voltage in response to a first control signal generated according to an output signal of the second differential input pair. When the output voltage reaches the first temperature-dependent voltage, the second switch is turned on to pull down the output voltage in response to a second control signal generated according to an output signal of the first differential input pair.
