rate (more pronounced for closer objects) and enhanced image clarity (Fig. 6.5.3(d)). Jiaqi Guo1, Junwei Feng1, Silin Chen1, Liuhao Wu1, Chne-Wuen Tsai1,2, Yingna Huang1, Bochi Lin1, Jerald Yoo1,2 To feed sufficient power to the 40kHz and 145kHz TX operation, a power-management unit (PMU) with high output power and voltage is needed. Using standard CMOS is more conducive to using existing IPs and more compatible with a wide range of processes. Therefore, we present a 0.98W output power Inductor-Shared Interleaved-Charging Hybrid Converter (IS-ICHC) with 14 Vout in standard CMOS. Figure 6.5.4(a) shows two hybrid converters in parallel which share a storage capacitor (C1-4) at each output voltage level (1-4VDDH). Power Stage A and Power Stage B are phase-shifted by 180°, so each storage capacitor is charged in an interleaved manner, achieving theoretically 2× larger output power than [3]. Since M1A, L1A, M2A, L2A have the same operating states as M2B,
Fig. 6.5.3(b). Compared to [3], there is a marginal reduction in the frame rate for images, beyond 1m. However, this is compensated by an additional 0.88× acceleration in frame
