Gierkink, Sander L.J. and Klumperink, Eric A.M. and Tuijl van, Ed and Nauta, Bram (1999) Reducing MOSFET 1/f Noise and Power Consumption by 'switched biasing'. In: 25th European Solid-State Circuits Conference, ESSCIRC '99, 21-23 Sept. 1999, Duisburg, Germany.
|Abstract:||"Switched Biasing" is proposed as a new circuit technique that exploits an intriguing physical effect: cycling a MOS transistor between strong inversion and accumulation reduces its intrinsic 1/f noise. The technique is implemented in a 0.8µm CMOS sawtooth oscillator by periodically off-switching of the bias currents during time intervals that they are not contributing to the circuit operation. Measurements show a reduction of the 1/f noise induced phase noise by more than 8 dB, while the power consumption is reduced by more than 30% as well.|
