Integrated ultra low leakage high voltage protection circuit |
摘要 |
An integrated high voltage device with an ultra low leakage input protection circuit to be used in highly sensitive circuits which require ultra low input leakage current. The protection circuit has a common substrate with the integrated circuit device and the common substrate is floating. The floating substrate provides a way of designing a protection circuit with small diodes which have ultra low input D.C. leakage. The protection circuit includes a resistor and two small Zener diodes which can clamp and protect the device during normal operating conditions up to voltages such as 1700 volts.
