Abstract: A composite MOS transistor (100) includes a first MOS sub-transistor (105) having a first gate dielectric thickness (106), and a second MOS sub-transistor (155) in series connection with the first MOS sub-transistor having a second gate dielectric thickness (107). The second gate dielectric thickness (107) is substantially thicker than the first gate dielectric thickness (106) preferably being at least 50% thicker. Composite MOS transistors generally provide a breakdown voltage (Vds) approaching that of the second MOS sub-transistor (155) and a threshold voltage, transconductance and drive current all approaching that of the first MOS sub-transistor (105), such as being within 20%, and preferably within 10%, of the reference parameter. A level shifting circuit includes first and at least a second drive transistor, wherein the drive transistors are composite MOS transistors.

Abstract: A high speed CMOS phase locked loop (PLL) (10) includes a three-state phase detection circuit having a frequency phase detector (12) coupled to a charge pump (14) for monitoring the phase differences between a reference frequency signal and a divided output frequency signal. The PLL can further include a loop filter (16)coupled to the three-state phase detection circuit, a VCO (18) coupled to the output of the loop filter, a VCO buffer (22) coupled to the output of the VCO for providing an output frequency signal, and a dual modulus prescaler (28) having a synchronous counter (27 and 29) using feedback among D flip-flops (30 and 32) for generating the divided output frequency signal.

Abstract: An integrated circuit for wireless communications includes substrate, at least one integrated antenna formed in or on the substrate, and a heat sink. At least one dielectric propagating layer is disposed between the integrated antenna and the heat sink which provides a thermal conductivity of at least 35 W/m·K and resistivity greater than 100 Ohm-cm at 25 C. The invention can be used to establish an on-chip or inter-chip wireless link over at least a 2.2 cm distance.
