Abstract:
This application relates to method and apparatus for driving acoustic transducers, such as speakers or haptic transducers. A transducer driver circuit ( 200 ) has a hysteretic comparator ( 201 ) configured to compare, with hysteresis, an input signal (S IN ) received at a first comparator input to a feedback signal (S FB ) received at a second comparator input. Based on the comparison the hysteretic comparator ( 201 ) generates a pulse-width modulation (PWM) signal (S PWM ) at a comparator output ( 206 ). An inductor ( 203 ) is coupled between the comparator output and an output node ( 204 ). In use a resistive component ( 208 ), which may comprise the transducer ( 301 ) is coupled to output node ( 204 ). The inductor ( 203 ) and resistive component ( 208 ) provide filtering to the PWM signal (S PWM ). A feedback path extends between the output node ( 204 ) and the second comparator input to provide the feedback signal (S FB ).

Claim (Index 11):
