摘要： A frequency divider circuit is provided having an even number of amplifier stages connected in series with the output of the last amplifier stage connected to the input of the first amplifier stage; and modulating means responsive to an input signal to be frequency divided, for modulating the propagation delay through each of the amplifier stages about the period of the input signal to be divided, such that when propagation through the odd amplifier stages increases, the propagation through the even amplifier stages decreases. The frequency divider circuit can be used as a pre-scaler of a radio receiver circuit.

摘要： The present system relates to a GNSS receiver that includes a processor. The processor is configured to receive a temperature signal from a temperature sensor indicating an operating temperature of an resonator. The processor is also configured to compute a frequency and a frequency correction data of the resonator based on the temperature and a frequency model of the resonator. The processor then transmits the frequency correction data to an RF receiver which utilizes the frequency correction data and the resonator to receive and RF signal.

摘要： A non-volatile memory cell comprising: a semiconductor substrate; a coupling capacitor located in a first active region of the semiconductor substrate; and at a shared second active region of the semiconductor substrate, a sense transistor and a tunnelling capacitor configured in parallel with the gate of the sense transistor; wherein the coupling capacitor, sense transistor and tunnelling capacitor share a common floating gate electrode and the sense transistor includes source and drain regions arranged such that the tunnelling capacitor is defined by an overlap between the floating gate electrode and the drain region of the sense transistor. The word-line contacts may be to a separate active area from the coupling capacitor. This and/or other features can help to reduce Frenkel-Poole conduction.
