CIRCUIT COMPRISING A CASCODE DEVICE AND METHOD OF OPERATING CIRCUIT

A circuit comprising a cascode device comprising a field effect transistor. The field effect transistor includes a common body region. The field effect transistor also includes a plurality of source regions. The source regions form inputs of the cascode device. Each source region of the plurality of source regions is separated from each other source region of the plurality of source regions by the common body region. The field effect transistor further includes a common gate. The field effect transistor also includes a common drain region. The common drain region forms an output of the cascode device. The circuit may further include a plurality of groups of one or more current sources each group coupled to a respective one of the inputs of the cascode device, and a current output coupled to the output of the cascode device. A method of operating a current source circuit.
