    摘要： Output buffer slew rate variation over variations in load capacitance is minimized by dividing output voltage transitions into distinct time and output current segments. During the first time segment, the first drive stage with the smallest current is employed. After subsequent delays, additional drive stages are employed and the load current is sequentially increased. Each drive stage employs a specifically sized feedback device which, depending upon its dimensions will provide either parasitic capacitance to slow transitions or positive feedback to speed up transitions. The first stages are sized to incorporate parasitic capacitance, resulting in little change in the settling time of small capacitance loads over prior art output buffers. Latter stages use positive feedback to quicken the transition time which dramatically improves the settling time for larger load capacitances over prior art output buffers.

    摘要翻译： 通过将输出电压转换分成不同的时间和输出电流段，可以最大限度地减小输出缓冲器的转换速率随负载电容变化的变化。 在第一时间段期间，采用具有最小电流的第一驱动级。 在随后的延迟之后，采用额外的驱动级，并且依次增加负载电流。 每个驱动级采用特定尺寸的反馈装置，其取决于其尺寸将为慢速转换提供寄生电容或提供正反馈以加速转换。 第一级的尺寸适合纳入寄生电容，导致小电容负载与现有技术输出缓冲器的稳定时间几乎没有变化。 后期阶段使用正反馈来加快转换时间，这大大提高了现有技术输出缓冲器对较大负载电容的稳定时间。

    摘要： A folded cascade receiver amplifier with constant gain has inputs coupled to PMOS and NMOS differential transistors pairs with scaled geometries. The transconductance of both PMOS and NMOS transistors is the same whether the common mode input voltage is low or high. In a first version the transconductance of both PMOS and NMOS differential transistor pairs is reduced when the common mode input voltage is at mid-rail. Resistive means between current sources and the sources of the PMOS and NMOS transistor pairs force the current source transistors into the triode region of operation. A second version insures a constant voltage gain through control means which maintain a constant ratio of the transconductance of the output stage transistors versus the PMOS and NMOS differential transistor pairs when active.

    摘要： A spread spectrum clock generator comprises a conventional closed-loop VCO and an open-loop VCO where both are coupled to the same point of the PLL. Both VCOs comprise a V-to-I converter followed by a current-controlled oscillator and are identical in design but only the open-loop VCO receives the modulation current to generate the spread spectrum clock signal. The open-loop ICO is part of the spread spectrum generator and in one embodiment of the invention receives feedback current signals representing the modulation method and modulation ratio. This ensures that the modulated clock output tracks the PLL output frequency. In a second embodiment the closed-loop VCO receives from the spread spectrum generator the feedback current signal representing the modulation method (center/down spread) while the open-loop VCO receives the feedback signal representing the modulation ratio.
