摘要： A Phase Lock Loop (PLL) with gain control is provided. The PLL has a dual-path configuration, where a first and a second VCO control voltage are generated in response to a phase or frequency difference between a PLL input signal and an output signal. The PLL comprises a dynamic voltage gain control (DVGC) unit and a voltage-to-current (V2I) unit, where the DVGC creates a baseline reference current in response to the first VCO control voltage and the V2I provides a substantially linear current in response to the second VCO control voltage. The currents from the DVGC and V2I are combined and fed into a current-controlled oscillator, which generates a PLL output frequency signal. Frequency gain of the VCO is substantially reduced, thus providing a PLL with improved tuning precision.

摘要： In one embodiment, the disclosure relates to a method and apparatus for inter-chip wireless communication system. The system includes a first microprocessor having a plurality of non-contact ports and a first RF communication circuit integrated with the first microprocessor; a second microprocessor also having a plurality of non-contact ports and a second RF communication circuit integrated therein. An RF communication protocol can be configured to receive data from each of the non-contact ports in parallel, multiplex and translate the data to a serial RF signal. Data communication can be accomplished using the wireless communication circuit on each chip. The RF communication between the first and the second integrated circuits using the communication protocol defines a non capacitive-coupling of the first and the second die.

摘要： A transceiver with a receive/transmit fast switch function according to the invention is disclosed. In the transceiver, a frequency generator is used to generate a carrier signal which is fed into a transmitter and a receiver. Furthermore, a frequency transfer circuit and a frequency synthesizer are used to generate first, second and third local oscillation signals which are fed into the transmitter and the receiver. When transmitting a signal, the transmitter receives the carrier signal and the first local oscillation signal. The carrier signal is up converted by a mixer and then transmitted by the antenna. Inversely, when receiving a signal, the receiver receives the signal from the antenna, the receive signal is down converted in coordination with the second and third local oscillation signals and then outputted. Moreover, the receive signal can be demodulated into an FSK signal by a discriminator.
