Abstract :
The fixed scale factors of analog integrated circuit trigonometric function converters limit their maximum input angular range. A method to increase the total input span is described. Experimental results demonstrate that the input range can be extended easily from the maximum value of ±3π to ±16π. By changing the hardware resolution, it may even be increased further. Factors which determine the angular resolution and linearity of the improved function converter are discussed
