The circuit arrangement (1) comprises an input (2) for the connection of an oscillator (3) and an amplifier circuit (20) having a first input (21) that is coupled to the input (1) of the circuit arrangement (1), having a second input (22) and an output (23) that is connected to an output (4) of the circuit arrangement (1). A clock signal (Vout) with a duty cycle (phi) can be accessed at the output (4) of the circuit arrangement (1) The circuit arrangement (1) furthermore incorporates a low-pass filter (40), the input of which is connected to the output (23) of the amplifier circuit (20), and an integrator circuit (50) the input of which is connected to the low-pass filter (40) and the output of which is connected to the second input (22) of the amplifier circuit (20) for the delivery of an adjustable threshold value (Vth) for controlling the duty cycle (phi).
