摘要： A reference power supply circuit includes an adjustable resistance network (12) and a bandgap reference power supply circuit (13). The adjustable resistance network (12) includes a first resistor end (PI) and a second resistor end (P2), and the resistance between the first resistor end (PI) and the second resistor end (P2) varies with a process deviation. The bandgap reference power supply circuit (13) connects the first resistor end (PI) with the second resistor end (P2). The bandgap reference power supply circuit (13) generates a positive proportional to absolute temperature current flowing through the first resistor end (PI) and the second resistor (P2), and outputs a reference voltage related to the positive proportional to absolute temperature current. The reference power supply circuit has the advantages of high precision and good temperature drift characteristic.

摘要： A pulse width modulation (PWM) comparator and a Class D amplifier are provided. In the PWM comparator, a current feedback mechanism is introduced, which is based on a waveform state of a received high frequency triangle signal and a level state of an output signal of the PWM comparator. The hysteresis of the PWM comparator is changed dynamically, so that the noise resistance ability of the PWM comparator is much better than that of the conventional PWM comparators having a fixed hysteresis. The PWM comparator can operate stably even if the duty cycle of the output signal is nearly 100%.
