Design of embedded sinusoidal signal generators for mixed signal Built-in Self-Test

Abstract : One of the main key points to enable mixed-signal BIST solutions is the development of efficient on-chip analog signal generators that can provide appropriate test stimuli and replace costly external signal generators in standard analog and mixed-signal functional test protocols. In this line, we present in this thesis different sinewave generation strategies based on harmonic cancellation techniques to design a high-frequency on-chip sinusoidal synthetize. The proposed generators employ digital hardware to provide a set of phase-shifted digital square-wave signals. These square-wave signals are scaled and combined using different harmonic cancellation strategies in a simplified current-steering DAC. The selected generator allows the cancellation of all harmonic components up to the eleventh. Additionally, a simple calibration strategy has been devised to compensate the impact of process variations and mismatch on the effectiveness of the harmonic cancellation. The simplicity of the circuitry makes this approach suitable for mixed-signal BIST applications. Electrical simulations of a 28nm FDSOI design and experimental results are provided to validate the functionality of the proposed signal generator. Obtained results show a calibrated performance around 52dB of SFDR for a generated sinusoidal signal at 166 MHz.
