Methods for generating a device layout are provided. First, design rules corresponding to a specific technology are received. A selection of at least one element and a parameter value corresponding to at least one parameter on the selected element are received. A draft device layout corresponding to the selected element is generated by a device generator by referencing the parameter value and the design rules. A script is then executed to modify the draft device layout to generate an updated device layout. The script includes at least one command, and when the script is executed, the at least one command is performed to modify the parameter value of the at least one parameter of the selected element and cause the device generator to delete the old draft device layout and generate a new draft device layout by referencing the modified parameter value and the design rules.

Class D amplifier is provided. The class D amplifier includes at least a block; each block includes an input circuit, an integrator, a comparator, a driving circuit and two feedback circuits. The input circuit receives a digital input to provide a differential pair of a positive and a negative input signals. The integrator receives the positive and negative input signals and a pair of positive and negative feedback signals for providing a positive error signal according to the positive input signal and the negative feedback signal, and providing a negative error signal according to the negative input signal and the positive feedback signal. The comparator compares between the positive and the negative error signals such that the driving circuit generates a driving output signal according to comparison result. The two feedback circuits respectively providing said positive and negative feedback signals according to the driving output signal.

A full digital soft-start circuit adapted for a power supply system is provided. The full digital soft-start circuit includes a ring oscillator, a pulse generator, a counter, and a multiplexer. The ring oscillator generates a plurality of clock signals which are different in phase, while equivalent in duty cycle and frequency. The pulse generator generates a plurality of pulse signals with different duty cycles. The counter generates a multi-bit counting signal. The multiplexer determines whether to transmit the pulse signals generated by the pulse generator so as to generate an output pulse which becomes stable as time going on.
