Abstract

La presente divulgación se refiere a un circuito de suministro de energía y un equipo electrónico, perteneciente al campo del circuito electrónico; el circuito de suministro de energía incluye: una batería, un chip de administración de energía y un chip de radiofrecuencia (RF); una terminal de salida de la batería es conectada al menos a una terminal de entrada del chip de administración de energía, mientras que al menos una terminal de entrada del chip de administración de energía es individualmente puesta a tierra a través de un condensador de filtro correspondiente, respectivamente; la terminal de salida de la batería también es conectada a una terminal de entrada del chip RF a través de un circuito de suministro de energía de conmutación; en la presente divulgación, se proporciona un circuito de suministro de energía de conmutación entre la terminal de salida de la batería y la terminal de entrada del chip RF, resolviendo así el problema de que un condensador de cerámica pueda liberar ruido audible cuando el chip RF envía una señal a una frecuencia requerida para la red de comunicación, y alcanzando el efecto de que el ruido producido por el condensador de cerámica, el cual puede seguir generando vibración, durante su vibración es inaudible para una persona ya que la frecuencia de conmutación del circuito de suministro de energía de conmutación es mucho mayor que una frecuencia audible para una persona.
