Abstract

"CIRCUITO INTEGRADO E DISPOSITIVO". Um dispositivo portátil de dados emprega um circuito integrado tendo um processador de sinal (112) que recebe um sinal de força de uma fonte externa (308) através de um nodo de força. Um dispositivo de desacoplamento (304) é colocado entre o nodo de força e o processador de sinal (112). Um reservatório de força (307) é colocado em paralelo ao processador de sinal (112), que atua em combinação com o dispositivo de desacoplamento (304) para isolar os efeitos do processador de sinal (112) do resto do circuito integrado.
