A Modified CMOS Differential-Pair-Based Triangular-and-Trapezoidal-to-Sine Converter

To simplify structure of a sinusoidal generator without serious performance degradation is one of major challenges in circuit design. An extremely simplified architecture triangular-and-trapezoidal-to-sine converter is presented. Curve of output signal, generated by the converter, is also low sensitive to temperature. Results from HSPICE simulations show that the approximated signal with a total harmonic content of 0.54 percent and an SFDR of –46 dBc at 1 kHz is achieved. The SDFR of output signal is adequate to be used in instrumentation systems.
