“…This system has flexibility, but its cost is relatively high and its size is large as well as the distortion of its generated signal may not be very low. The third method is the usage of the digital ATE eliminating the need for an IEICE Electronics Express, Vol.VV, No.NN, 1-6 analog option [18,19]. There the harmonics of a rectangular wave are suppressed by a high order and high performance analog filter, which may be large, and expensive [30].…”

“…Compared to a 16-bit direct digital synthesizer (DDS) sinusoidal signal generator with equivalent performance to the ATE system one, the proposed generator further reduces HD3 by 3 dB and in-band noise by 10 dB, which results in harmonic distortion of −95 dBc for 100 kHz sinusoidal signal generation. Notice that sinusoidal signals are widely used as input signals for AC characteristics and linearity testing of AMS circuits [4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19]. This is because their low distortion generation is relatively simple, compared to the ramp signal.…”

This paper proposes a low-distortion sine wave generator using logic circuits and relatively simple analog filter for analog device testing. Our proposed circuit cancels 3rd-order harmonic distortion (HD3) and 5th-order harmonic distortion (HD5) by summing multiple rectangular waveforms of fundamental and higher frequencies. These rectangular waves are generated by appropriately dividing the rectangular wave from a digital automatic test equipment (ATE). The other higher order odd harmonics are removed by the following simple analog low-pass filter (LPF). We have implemented its prototype whose measurement results show the generation of a sine wave with harmonics of less than −95 dBc.
