Abstract
A class-D amplifier includes: a p-type output transistor; an n-type output transistor connected in series with the p-type output transistor; and a drive circuit connected to a gate of the p-type output transistor and a gate of the n-type output transistor. The drive circuit receives an input signal, generates a p-type output transistor control signal applied to the gate of the p-type output transistor, and generates an n-type output transistor control signal applied to the gate of the n-type output transistor. When the input signal becomes logic high, the n-type output transistor control signal becomes logic low fast, while the p-type output transistor control signal becomes logic low gradually. When the input signal becomes logic low, the p-type output transistor control signal becomes logic high fast, while the n-type output transistor control signal becomes logic high gradually.
