“…This is an advantage compared to previously presented generators using harmonic cancelation such as [6,7,18]. These previous works are based on matching different stages for the generation of time-delayed signals, so any mismatch between the stages has a negative impact on the harmonic cancellation.…”

“…Some recent proposals for sinusoidal signal generation combine a closed-loop oscillator and a harmonic cancellation technique to provide highly linear sinusoidal signals [6,7,18]. These techniques are based on the fact that adding time-shifted versions of a periodic waveform it is possible to cancel some of the harmonic components in the original waveform.…”

“…On the other hand, the approach in [7,18] is based on combining the outputs of a phase-shift oscillator. The work demonstrates that by properly weighting and summing the output signals of a phase-shift oscillator, it is possible to obtain sinusoids with a very low harmonic distortion.…”

“…Combining a high number of signals would allow the cancellation of different harmonic components at the same time, as it is demonstrated in [7], but this would also increase the complexity of the input stage of the generator. Given that our generator is intended for onchip test applications, increasing the complexity -which in turn may increase the overhead-is to be avoided.…”

“…Filtering : After harmonic cancellation, higher order harmonic components will be attenuated by the generator itself according to equation (7). Then, regarding the system transfer function H(s), we need to match its shape to the frequency of interest in the application.…”

This work presents a technique for the onchip generation of analog sinusoidal signals with high spectral quality and reduced circuitry resources. The proposed generation technique consists of a modified low-order analog filter, that provides a sinusoidal output as response to a DC input, combined with a harmonic cancellation strategy to improve the linearity of the generated signal. The proposed generator has the attributes of digital programming and control, low area overhead, and low design effort, which make this approach very suitable as test stimulus generator for builtin test applications. An integrated prototype designed in a 180nm CMOS technology is presented in order to show the feasibility of the technique. Results obtained from the prototype show a THD around −80dB.
