摘要： A structure that reduces signal cross-talk through the semiconductor substrate for System-On-Chip (SOC) (2) applications, thereby facilitating the integration of digital circuit blocks (6) and analog circuit blocks (8) onto a single IC. Cross-circuit interaction through a substrate (4) is reduced by strategically positioning the various digital circuit blocks (6) and analog circuit blocks (8) in an isolated wells (10), (12), (16) and (20) over a resistive substrate (4). These well structures (10), (12), (16), and (20) are then surrounded with a patterned low resistivity layer (22) and optional trench region (24). The patterned low resistivity region (22) is formed below wells (10) and (12) and functions as a low resistance AC ground plane. This low resistivity region (22) collects noise signals that propagate between digital circuit blocks (6) and analog circuit blocks (8).

摘要： Apparatus are provided for voltage-controlled oscillators (VCOs) and related systems. An exemplary VCO includes an active-circuit arrangement employing cross-coupled amplifying elements that facilitate generation of an oscillating signal, plus a resonator arrangement capacitively coupled via resonator terminals to primary terminals of the active-circuit arrangement, to influence an oscillation frequency of the oscillating signal based on a difference between control voltages applied to first and second control terminals of the resonator arrangement. When employing bipolar amplifying elements their control terminals are cross-coupled to the opposing resonator terminals. VCO output may be taken from the primary terminals or from the resonator terminals.
