“…A dedicated oscillator circuit may generate a very low distortion sinusoidal signal, but it may raise the issues of inflexibility as well as high cost and large size. Another method is the usage of an arbitrary waveform generator (AWG) in an analog module on ATE [4,5,6,7,8,9,10,11,12]. It generates a waveform using waveform memory data, feeding them to the DAC and removing image components in its analog output by the following analog filter.…”

“…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.

“…An arbitrary waveform generator (AWG) consists of a DSP (or waveform memory) and a digital-to-analog converter (DAC) [2][3][4][5][6][7][8][9]. We can use the AWG to generate arbitrary analog waveforms simply by changing the DSP program [2][3][4][5][6][7][8][9], and Automatic Test Equipment (ATE) often uses AWGs [9]. However, due to AWG nonlinearities, sinusoidal signals generated by AWGs include harmonics that degrade the accuracy of analog/mixed-signal circuit testing when the generated signals are used for the testing input.…”

This paper describes analysis, simulation and experiment verification of high-frequency one-tone and two-tone low-distortion signal generation methods with an arbitrary waveform generator (AWG) for analog/mixed-signal IC testing. Our previously proposed phase switching method was limited to low-frequency signal generation, and it cannot be used directly for high-frequency signal generation. We propose here a method for generating a low-distortion high-frequency signal (i.e., the frequency close to the Nyquist frequency of the AWG) with an AWG, and show its theoretical analysis and simulation results. With this proposed method, 3rd order harmonics of the generated signal are suppressed simply by changing the AWG program (or waveform memory contents)—AWG nonlinearity identification is not required—and spurious components, generated far from the signal band, are relatively easy to remove using an analog filter.
