Autor: Siniscalchi, Mariana; Podevin, Florence Resumen: Held on Wednesday, 28 February 2024, from 17:30 to 20:30, in Punta del Este, Uruguay, the Women in Circuits and Systems (WiCAS) event was a collaborative effort organized by Mariana Siniscalchi (Universidad de la República, Uruguay) and Florence Podevin (Université Grenoble Alpes, France). The event was integrated into the International Symposium of the IEEE Circuits and Systems Society (LASCAS 2024), emphasizing the theme “Women in Circuits and Systems: Rhythm of Progress, Focusing on Inclusion.” The event aimed to celebrate and empower women in engineering while advocating for diversity and equal opportunities. It comprised three segments.

These models consider one to four extra parameters in addition to the three basic parameters of the long-channel transistor compact models, which are the slope factor, the equilibrium threshold voltage and the normalization current. An acceptable accuracy of the dc characteristics and the small-signal parameters is obtained through these models. This work analyzes whether it is possible to obtain an adequate model of the intrinsic part of the capacitances by means of these models and parameters, while proposing a simple method to account for the extrinsic part of the capacitances. The proposed method, together with the model, is tested for minimum-length transistors in an FD-SOI 28 nm process and applied to the design of a low-voltage LC oscillator. The results obtained by these means are compared with the results of a look-up table approach and with simulation results, showing a reasonable agreement.

It captures key parameters—capacitances, transition frequency, hysteresis thresholds, output current, and time constants—with good agreement to circuit-level simulations. Complementing existing models, it provides fast and reliable estimates for transistor sizing and reduces the need for extensive simulations, offering a practical tool for the design and analysis of ultra-low-voltage circuits.

Following a previous work, it is predicted that 0.26 V is the minimum supply voltage of this VCO. It was verified through simulations that the VCO can operate with 0.25 V supply, consuming 90 μW and has a phase noise of -90.2 dBc/Hz at 1 MHz, while complying with the requirements of the following stage. As a consequence of operating at frequencies above the transition frequency of the transistors, the predictions based on the previous study, are less accurate but still provide a good starting point for the design. Moreover, lifting the previous study hypothesis of having an oscillation frequency at least a decade below the transition frequency of the transistors has allowed to further lowering the minimum supply voltage.
