    摘要: An integrated circuit including a Phase Locked Loop (PLL) configured for use with a continuous stream receiver is disclosed. A control voltage line is configured to deliver a control voltage with a capacitive load delivered by a capacitor array to the control voltage based upon an add signal and a subtract signal. A threshold generator generates a high threshold voltage and a low threshold voltage using and including at least one process dependent resistor and at least two temperature and process dependent current sources. The PLL responds during calibration to the control voltage being above the high threshold voltage by asserting the add signal directing the capacitor array to increase the capacitive load on the control voltage line, and to the control voltage being below the low threshold voltage by asserting the subtract signal to decrease the capacitive load.

    摘要: A differential latch circuit with a differential reset function includes a first arrangement of transistors configured to perform a latch function and a second arrangement of transistors, connected to the first arrangement of transistors, configured to perform a reset function. The first arrangement of transistors includes branches having three cascoded transistors, and the second arrangement of transistors includes branches having two cascoded transistors. This configuration enables the latch circuit to use lower power supply voltages relative to conventional latch circuits that require four more cascoded transistors.
