Title:
SIGNAL CONVERTING CIRCUIT AND ISOLATION AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2009/155744
Kind Code:
A1
Abstract:
A signal converting circuit comprises: a diffluent-type voltage reference circuit (201) for setting a reference voltage signal; an addition circuit (202) connected to the diffluent-type voltage reference circuit (201), for receiving the inputted voltage signal, and adding the reference voltage signal set by the diffluent-type voltage reference circuit (201) to the inputted voltage signal to obtain the added voltage signal; a voltage-current converting circuit (203) connected to the addition circuit (202), for converting the added voltage signal into the output current signal. An isolation amplifier comprises the signal converting circuit. With the technical solution mentioned above, it is possible to converting the input signal into the output signal integrally.
