Abstract:
1. A galvanic isolator comprising: a transmitter die comprising an LED having first and second contacts for powering said LED; a receiver die comprising a photodetector; a lead frame comprising first and second transmitter leads, and first and second receiver leads, said transmitter die being bonded to said first transmitter lead, said first contact being connected electrically to said first transmitter lead and said second contact being connected to said second transmitter lead, and said receiver die being connected to said first and second receiver leads, wherein said LED and said photodetector are positioned such that light generated by said LED is received by said photodetector, and wherein said first and second transmitter leads are capacitively coupled to said first receiver lead, said capacitive couplings being characterized by first and second capacitance values, said first and second capacitive values being substantially the same.
