A novel flying-capacitor-clamped five-level inverter based on bridge modular switched-capacitor topology is proposed in this paper. The inverter features the switched-capacitor circuit with dc–dc boosting conversion ability and the multilevel inverter circuit with flying-capacitor-clamped performance. With the special composite structure, the number of components is cut down compared to the topology...
This paper presents a 0.8V analog front-end (AFE) with referenceless time-based digitalization architecture for electrocardiogram (ECG) signal acquisition. Compared to the conventional voltage-domain architecture, the proposed AFE achieves a smaller chip area, lower power consumption, and self-calibration without the high-accuracy clock as well as voltage reference. The chip is fabricated using 0...
This study develops a dual-path cross-correlation technique and a single-path cascade method for phase noise and transient measurements up to the V-band frequency region. Further, this paper presents the complete test setup and test procedure. Results of the analyses of the single-path cascade measurement method and the signal-to-noise ratio (SNR) floor effects are also discussed in detail. We demonstrate...
