    • A low noise VCO circuit for an LC VCO circuit comprising MOS varactors is disclosed. The LC VCO circuit usually comprises an LC tuning circuit coupled with a pair of cross-coupled transistors used as a negative impedance element. A pair of varactors is used to provide fine tuning by applying a control voltage to the varactor. Since the varactor is also coupled to the pair of cross-coupled transistor, the process variation and temperature change may affect the bias voltage coupled to the pair of varactors. Therefore, a bias circuit usually is used to alleviate the impact of process variation and temperature change associated with the pair of transistor. Nevertheless, the bias voltage typically is implemented by providing a current flowing through a resistor, wherein the current is generated by a current source. The noise associated with the current source will affect the performance of the VCO circuit. A low noise VCO circuit is disclosed which utilizes a low noise bias circuit. The low noise bias circuit comprises a current source, a load device and a voltage divider wherein the load device is coupled to the voltage divider in parallel. The load device may be implemented using a bipolar transistor or a diode-connected MOS device.
    • 公开了一种用于包括MOS可变电抗器的LC VCO电路的低噪声VCO电路。 LC VCO电路通常包括与用作负阻抗元件的一对交叉耦合晶体管耦合的LC调谐电路。 一对变容二极管用于通过对变容二极管施加控制电压来提供微调。 由于变容二极管还耦合到一对交叉耦合晶体管,所以工艺变化和温度变化可能影响耦合到该对变容二极管的偏置电压。 因此,偏置电路通常用于减轻与该对晶体管相关的工艺变化和温度变化的影响。 然而,偏置电压通常通过提供流过电阻器的电流来实现,其中电流由电流源产生。 与电流源相关的噪声将影响VCO电路的性能。 公开了一种利用低噪声偏置电路的低噪声VCO电路。 低噪声偏置电路包括电流源,负载装置和分压器,其中负载装置并联耦合到分压器。 负载装置可以使用双极晶体管或二极管连接的MOS器件来实现。

    • An apparatus for demodulating an analogue input signal comprises a hard limiter stage (4) for converting the signal to a two level signal. A digital down converter/low pass filter stage (6) converts the signal to a base band signal, and a symbol synchronization stage (8) extracts symbol timing. An instantaneous phase detector (10) calculates the instantaneous phase of the one or more symbols associated with the input signal. If the input signal has been modulated according to a pi/4DQPSK, pi/2DBPSK, GMSK, or a GFSK modulation scheme, a differential detector (12) determines a difference in the phase between adjacent symbols, a coarse frequency offset compensation stage (14) applies a compensation signal to compensate for frequency offset, and a frequency offset estimation stage (16) updates this compensation signal. A demapper (18) generates a demodulated output signal after compensation by the frequency offset compensation stage.
