Abstract: This paper presents the design of a new Wienbridge topology. Its phase noise performance, low temperature dependency and low power consumption make it suitable for use in wireless sensor nodes and time-based sensor readout circuitry. The noise as well as temperature behavior of the oscillator is explained using extensive calculations. Measurements on 7 samples of the same batch show a temperature stability of 86 ppm C and a measured spread of 0.9% at an oscillation frequency of 6 MHz. The circuit consumes 66 Wand is realized in a 65 nm technology measuring 150 m by 200 m. The measured phase noise figure
of merit is 172 dB at a frequency offset of 100 kHz.
