Patent attributes
p-channel MOS transistors are turned on alternatively when a positive phase signal and an opposite phase signal each generated from a first voltage signal. Moreover, n-channel MOS transistors are turned on alternatively when a positive phase signal and an opposite phase signal each generated from a second voltage signal. When being turned on, the p-channel MOS transistors supply current to transmission lines, respectively. When being turned on, the n-channel MOS transistors discharge current supplied from the transmission lines to a ground. A current to voltage conversion circuit converts current passing through the transmission lines into a voltage signal. Another current to voltage conversion circuit converts current passing through another transmission lines into a voltage signal.
