  • Patent number: 6396354
    Abstract: Phase locked loop (PLL) detection circuit that can improve the stability of operation, avoid occurrence of an erroneous operation, and perform PLL lock judgment correctly. Whether a PLL circuit that consists of a phase comparator, a low-pass filter, and a VCO is in a lock state is judged based on a phase error signal in the PLL circuit. The level of the phase error signal is compared with two threshold values, VRL and VRH. When the phase error signal is somewhere between VRL and VRH, a judgment is made that the PLL circuit is in a lock state. A judgment that the PLL circuit is out of a lock state is made in the other cases. This makes it possible to output a correct and stable PLL lock judgment signal.

    Abstract: A high impedance circuit capable of operating at a low voltage without narrowing the dynamic range is provided, which includes a first and a second transistors forming differential-pair type circuit, a third and fourth transistors, a pair of collector resistance elements, a resistance element and a pair of current source circuits. The third and the fourth transistors serve as emitter follower circuits which also functions as a DC shift with respect to the differential-pair type circuit, as well as buffer circuits for heightening an input impedance of the first and the second transistors looked from the base side of the third and the fourth transistors. The current flowing in the resistance element is made current-fedback with respect to the resistance elements by the third and the fourth transistors. The input impedance is determined as Z1=V1/ i3=(R1×R2)/(R1−R2), and when R1=R2, the high impedance circuit becomes infinite impedance.
