Abstract

Un circuito (800) para controlar por lo menos un accionador (142) piezoeléctrico incluye un circuito (802) de excitación piezoeléctrico que genera la señal de excitación de voltaje unidireccional, también denominada como Vout, en el nodo (804). El circuito (802) de excitación del accionador piezoeléctrico incluye un circuito conmutador de refuerzo o circuito (806) de carga, un circuito conmutador de oposición o circuito (808) de descarga de disipación de corriente impulsada y un circuito (810) de generación de señales de control que recibe una señal (802) de control de entrada de, por ejemplo, un procesador de teclado u otro procesador (604) adecuado que indica que el dispositivo ha solicitado la generación de realimentación háptica que utiliza el accionador (142) piezoeléctrico. El circuito (810) de generación de señales de control proporciona por lo menos dos señales de control moduladas por amplitud de impulsos, una para controlar el circuito de carga y otra para controlar el circuito de descarga para producir la señal de excitación de voltaje unidireccional, que en un ejemplo es una señal (904) de excitación de coseno elevado.
