Abstract :
A bandpass sigma delta modulator is proposed with a noise transfer function that is tunable by means of one parameter only. The centre frequency can be tuned in the range between DC to half the sampling frequency. The modulator stability and nearly constant resolution for the whole frequency range are demonstrated.
