Oscillator compensation using bias current

In one embodiment, an apparatus includes: a bias circuit having a replica circuit, the bias circuit to generate an oscillator current that is proportional to a variation of the replica circuit; an oscillator circuit coupled to the bias circuit to receive the oscillator current and generate a plurality of signals using the oscillator current; and a waveform shaper circuit coupled to the oscillator circuit to receive the plurality of signals and generate at least one clock signal from the plurality of signals. 在一个实施例中，一种装置包括：具有复制电路的偏置电路，所述偏置电路用于生成与复制电路的变化成比例的振荡器电流；耦合到偏置电路的振荡器电路，用于接收振荡器电流并且使用振荡器电流生成多个信号；以及耦合到振荡器电路的波形整形器电路，用于接收多个信号并且从多个信号生成至少一个时钟信号。
