Title:
SIGNAL TRANSMISSION CIRCUIT AND ENDOSCOPE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/056146
Kind Code:
A1
Abstract:
Provided is a signal transmission circuit having an impedance conversion circuit and a current-voltage conversion circuit. A first current is inputted to the impedance conversion circuit. The impedance conversion circuit outputs a second current that corresponds to the first current. The current-voltage conversion circuit converts the second current outputted from the impedance conversion circuit into a voltage. The impedance conversion circuit has a first current source and a current output circuit. The first current source generates a reference current. The current output circuit outputs the second current, which corresponds to a difference between or the sum of the first current and the reference current.
