Integrated circuit for portable telephone, has cell with flip-flop, and output voltage setting unit regulated by control signal which depends on mode signal that indicates whether circuit is in operation mode or in test mode

摘要

The circuit has a cell (34), which has an output with a fixed output voltage when the circuit is in operation mode. The cell has a flip-flop (11) and a unit (31) for setting the output voltage when the circuit is in the operation mode. The unit (31) is regulated by a control signal, which depends on a mode signal (15) that indicates whether the circuit is in the operation mode or in the test mode.
