Abstract :
A novel circuit configuration for generating the sine function in MOS integrated circuit technology is proposed. It is based on the exponential-law of MOS transistors operating in the subthreshold region. An experimental MOS sine generator and PSPICE simulations show that the MOS sine function generator achieves a total harmonic distortion of 0.71% over an angular range of +or-360 degrees . Typical power consumption is less than 1 mu W and the bandwidth is greater than 100 kHz.
