Abstract
A low-pass filter includes an integrator having an adjustable unity frequency. The integrator includes a first input, first output and feedback loop between the first input and output of the integrator. The first input is connected to a branch that includes a first impedance, to which is applied a first input voltage of the low-pass filter. The feedback loop includes a second impedance and the first output of the integrator is the first output of the low-pass filter.
