放大器及其放大方法
摘要：
种放大器及其放大方法。该放大器包括第混合长度装置组与第负载电路。第混合长度装置组用以接收输入信号并输出输出信号,而第负载电路用以提供输出信号的终端。第混合长度装置组包括并联的不同通道长度的多个金属氧化物半导体(MOS)装置,并且此些MOS装置至少包括短通道长度MOS装置与长通道长度MOS装置。其中,短通道长度MOS装置的临界电压高于长通道长度MOS装置的临界电压。
摘要（英）：

An amplifier is provided having a first mixed-length MOS device set for receiving an input signal and outputting an output signal, and a first load for providing termination for the output signal, wherein the first mixed-length MOS device set comprises a parallel connection of a plurality of MOS devices having different channel lengths including at least a short channel length MOS device and a long channel length MOS device. In one configuration, a threshold voltage of the short channel length MOS device is greater than a threshold voltage of the long channel length MOS device. A related method is also provided.
