    摘要： A clamped linear transconductance amplifier path, consisting essentially of a current clamp (M23) merged in a linear transconductance amplifier (M23, M21,M22) path, is used in a triple-input, single-output transconductor (200). In a balanced transconductor in CMOS technology, this clamped linear transconductance amplifier path is formed by a p-channel MOS transistor (M23) separately connected in series with each of a matched pair of p-channel MOS transistors (M21, M22). The clamped linear transconductance amplifier path, together with two other transconductance paths (M15-M20; M9-M14), can be interconnected to form the input side of the triple-input, single-output transconductor (200). By summing and integrating the outputs of the input side of the triple-input transconductor (200), the output (VOUT,P and VOUT,N) of the output side of the transconductor can be formed. By feeding back this output to the input side of the transconductor (200), an oscillator can obtained.

    摘要翻译： 夹紧线性跨导放大器路径，基本上由电流钳（M23）的以线性跨导放大器（M23，M21，M22）的路径，是在三输入，三输出跨导器（200）使用合并。 在CMOS技术中一个平衡跨，此夹紧线性跨导放大器路径由一个p沟道MOS晶体管（M23）分别串联连接各一对匹配的p沟道MOS晶体管（M21，M22）的形成。 被夹紧的线性跨导放大器路径，与其他在一起的两个跨导路径（M15-M20; M9-M14），可以相互连接以形成三输入的输入侧，三输出跨导器（200）。 通过求和与INTEGRA婷三重输入跨（200）的输入侧的输出，跨导器的输出侧的输出（VOUT，P和V OUT，N）可以被形成。 通过反馈该输出到振荡器的跨导器（200）的输入侧可以得到。
