  • Input amplifier for input signals with steep edges
    Patent number: 6008695
    Abstract: An input amplifier for input signals with steep edges has a MOS transistor, whose source or drain is connected to a node connected to an output stage. The output signal is fed back into the amplifier which prevents the MOS transistor from being turned off by steep edge input signals. The node is pulled up to the operating voltage as soon as the input signal is present.
