  • Input stage for a sample analog to digital converter, sample analog to digital converter and procedure for testing an analog to digital converter
    Patent number: 12068754
    Abstract: An input stage for an analog/digital converter, an analog/digital converter and a method for testing analog/digital converters with successive approximation are disclosed. At an input stage, an input signal is supplied via a first transistor arrangement of a sampling capacitor arrangement. The sampling capacitor arrangement can be optionally connected to ground or to a reference voltage by way of a second transistor arrangement and a switch apparatus.
    Type: Grant
