A pair of transistors forming a half-bridge that supplies an output signal at an output terminal of the amplifier are operated so that neither transistor is fully on during an overlap time period. A current source provides an output current to the output terminal during the non-overlap time period to control the output voltage while changing the transistor that conducts the output current from a first one of the pair of transistors to a second one of the pair of transistors. The current source may be provided by operation of one of the transistors in a current source configuration. The voltage of a gate of one of the transistors can be compared with a threshold to provide an indication of the current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pulse-width modulated (PWM) audio power amplifier with output transition slope control","description":"An audio switching power amplifier having an output with controlled-slope transitions maintains efficiency while avoiding uncontrolled non-overlap intervals during switching transitions.
