A converter circuit receives the transformed AC power signal and then converts the signal into a DC power signal supplied to one or more function circuit. The transformed AC power signal might either be stepped up or stepped down. The transformer circuit might comprise two coils, where a first coil is magnetically coupled to a second coil. The first coil is a first spiral and the second coil is a second spiral wherein an insulating material layer is disposed between the first spiral and the second spiral. The transformer circuit might include transformers connected in parallel or in series and may further be connected correspondingly to more than one converter circuit coupled in parallel.

摘要： A bi-directional communication system and transceiver configuration are described, which employ a bi-directional reference to account for both common-mode and differential noise introduced at either end of a bi-directional communication channel. Some implementations exploit the techniques described in a bi-directional chip-to-chip communication scheme. In some implementations, the advantages of bi-directional reference techniques described herein are obtained while pre-distortion of transmitted signals is employed to compensate for intersymbol interference (ISI) in a communications channel.

摘要： A clock buffer circuit utilizing an LC circuit for jitter reduction. The circuit includes a differential amplifier that is coupled to a buffer stage. The output of the buffer circuit comprises the buffer stage output. An inductor and capacitor are coupled between the buffer stage output and ground. The values of the inductor and capacitor are specified such that the resonant frequency of the LC circuit corresponds to the nominal clock frequency. The entire buffer circuit including the capacitor and inductor may be fabricated on an integrated circuit. Alternatively the capacitor and/or inductor may comprise discrete components that are coupled to the buffer stage output. Additionally, multiple capacitors and/or inductors may be fabricated on the integrated circuit to permit the resonant frequency of the LC circuit to be adjusted to match the nominal clock frequency. The capacitor(s) and/or inductor(s) on the integrated circuit may be connected to integrated circuit contacts and coupled to the buffer stage output via external connections or alternatively, via semiconductor switches.

摘要： A clock recovery system that allows recovery of a clock signal from a high speed, potentially small amplitude data stream. The invention uses a normally avoided property of a non-linear oscillator in the clock recovery system in order to lock the oscillator in phase to an incoming signal. This property relates a characteristic of an oscillator that an oscillator amplifies noise near its inherent frequency; and if the noise is large enough, the oscillator squelches the inherent oscillator frequency signal and outputs a signal locked in frequency and phase to the noise. The clock recovery system comprises a processing circuit, an oscillator, and a control circuit. The processing circuit processes an input data stream to generate a current signal as a first control signal based on data transitions in the input data stream. The first control signal is a "noise signal" to the oscillator. The control circuit outputs a voltage control signal as a second signal to the oscillator based on a difference between an output fed back from the oscillator and a reference frequency signal matching the frequency of the input data stream within a predetermined tolerance range. The second control signal controls the oscillator so that the frequency of the oscillator output is substantially equal to that of the input data stream. Therefore, according to the invention, the oscillator is controlled by the first control signal such that the oscillator output is phase-locked and thus also frequency-locked to the input data stream.
