Title:
TRANSIENT VOLTAGE ABSORBING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/196642
Kind Code:
A1
Abstract:
A transient voltage absorbing circuit (101) comprises impedance elements (Z1, Z2) connected in series to a signal line (SL), and a transient voltage absorbing element (11) connected as a shunt between the signal line (SL) and a reference potential. The transient voltage absorbing element (11) has a floating capacitance component across terminals. The impedance of the impedance elements (Z1, Z2) and the floating capacitance component of the transient voltage absorbing element (11) have values such that a low-pass filter composed of the impedance elements (Z1, Z2) and the transient voltage absorbing element (11) exhibits a Butterworth characteristic.
