摘要： One or more techniques and systems for a divider-less phase locked loop (PLL) and associated phase detector (PD) are provided herein. In some embodiments, a pulse phase detector (pulsePD) signal, a voltage controlled oscillator positive differential (VCOP) signal, and a voltage controlled oscillator negative differential (VCON) signal are received. An up signal and a down signal for a first charge pump (CP) and an up signal and a down signal for a second CP are generated based on the pulsePD signal, the VCOP signal, and the VCON signal. For example, CP signals are generated to control the first CP and the second CP, respectively. In some embodiments, CP signals are generated such that the CPs facilitate adjustment of a zero crossing phase of the VCON and VCOP signals with respect to the pulsePD signal. In this manner, a divider-less PLL is provided, thus mitigating PLL power consumption.

摘要： A built-in self-test circuit for testing a voltage controlled oscillator comprises a voltage controlled oscillator, a buffer having an input coupled to an output of the voltage controlled oscillator and a radio frequency peak detector coupled to the output of the buffer. The radio frequency peak detector is configured to receive an ac signal from the voltage controlled oscillator and generate a dc value proportional to the ac signal at an output of the radio frequency peak detector. Furthermore, the output of the radio frequency peak detector generates a dc value proportional to an amplitude of the ac signal from the voltage controlled oscillator when the voltage controlled oscillator functions correctly. On the other hand, the output of the radio frequency peak detector is at zero volts when the voltage controlled oscillator fails to generate an ac signal.

摘要： A level shifter includes an input node, an output node, a pull-up transistor, a pull-down transistor, and at least one diode-connected device coupled between the pull-up transistor and the pull-down transistor. The level shifter is arranged to be coupled to a high power supply voltage, to receive an input signal having a first voltage level at the input node, and to supply an output signal having a second voltage level at the output node. The high power supply voltage is higher than the first voltage level. The at least one diode-connected device allows the output signal to be pulled up to about a first diode voltage drop below the high power supply voltage and/or to be pulled down to about a second diode voltage drop above ground. The first diode voltage drop and the second diode voltage drop are from the at least one diode-connected device.
