Problems solved by technology

Furthermore, when the number of cascode stages increases, the active control means S1, S2 increase the complexity of the cascode circuit, so that said cascode circuit is no longer practical
Therefore, the maximum voltage Vin that can be switched by means of a cascode circuit in an economical manner is limited

Abstract

In various embodiments, a circuit (300a, 400a, 1100b) is provided. The circuit may include a plurality of cascode stages (102a, 102b) connected in series with one another, a voltage divider which is connected in parallel with the plurality of cascode stages (102a, 102b) and is coupled to the cascode stages (102a, 102b) in order to make available a first electrical backup potential (Vs1) at at least one cascode stage (102a, 102b)of the plurality of cascode stages, and a controller (106) which is configured to couple the at least one cascode stage of the plurality of cascode stages(102a, 102b) to a predefined second electrical backup potential (Vcasc) if a voltage which is present at the voltage divider satisfies a predefined criterion.

Description

technical field [0001] The invention relates to a circuit and a method for operating the circuit. Background technique [0002] Typically, integrated circuits (also known as chips or microchips) can be used to process digital or analog signals. An integrated circuit can have a plurality of electrical components whose electrical interconnection is designed according to one or more functions of the integrated circuit. For example, an electrical device by means of an integrated circuit is capable of processing signals or performing switching operations. Certain areas of application may require the processing of voltages or signals by means of integrated circuits which exceed the electrical loadability of the individual electrical components (eg breakdown voltage). Alternatively or additionally, the miniaturization of electrical components can lead to a reduction in their electrical loadability, so that the maximum voltage for operating the integrated circuit can be reduced. ...
