ABSTRACT:
An integrated circuit may include an inverter which may include a first transistor of a first conductivity type and a second transistor of a second conductivity type connected in parallel with the first transistor. An input of the inverter may be capable of receiving an oscillating input signal, and which may include an output of the inverter, which is connected to a capacitive device capable of being charged and discharged depending on the state of the first and second transistors being on or off. The inverter may be capable of delivering an oscillating output signal at its output. The integrated circuit may include a selector for transmitting the oscillating output signal and for masking the charging and/or discharging of the capacitive device.
