Abstract: An all-digital phase locked loop (ADPLL) receives an analog input supply voltage which is utilized to operate analog circuitry within the ADPLL. The ADPLL of the present disclosure scales this analog input supply voltage to provide a digital input supply voltage which is utilized to operate digital circuitry within the ADPLL. The analog circuitry includes a time-to-digital converter (TDC) to measure phase errors within the ADPLL. The TDC can be characterized as having a resolution of the TDC which is dependent, at least in part, upon the digital input supply voltage. In some situations, process, voltage, and/or temperature (PVT) variations within the ADPLL can cause the digital input supply voltage to fluctuate, which in turn, can cause fluctuations in the resolution of the TDC. These fluctuations in the resolution of the TDC can cause in-band phase noise of the ADPLL to vary across the PVT variations. The digital circuitry regulates the digital input supply voltage to stabilize the resolution of the TDC across the PVT variations. This stabilization of the resolution of the TDC can cause the ADPLL to maintain a fixed in-band phase noise across the PVT variations.

Abstract: A semiconductor package includes a first semiconductor device, a second semiconductor device vertically positioned above the first semiconductor device, and a ground shielded transmission path. The ground shielded transmission path couples the first semiconductor device to the second semiconductor device. The ground shielded transmission path includes a first signal path extending longitudinally between a first end and a second end. The first signal path includes a conductive material. A first insulating layer is disposed over the signal path longitudinally between the first end and the second end. The first insulating layer includes an electrically insulating material. A ground shielding layer is disposed over the insulating material longitudinally between the first end and the second end of the signal path. The ground shielding layer includes a conductive material coupled to ground. The ground shielding layer drives radiation signals received therein to ground to prevent induced noise in the first signal path.
