    • A frequency selective differential amplifier (400) consistent with certain embodiments of the invention has a plurality of N amplifier stages (401, 402, 403 through 404) that collectively drive load (410). The plurality of N amplifier stages (401, 402, 403, . . . , 404) have input nodes and output nodes. A plurality of N−1 output phase shift circuits (421, 422, . . . , 423) connect the output nodes of the plurality of amplifier stages in a manner that causes output signals from the plurality of output nodes to add together for delivery to the load (410), the plurality of output phase shift circuits (421, 422, . . . , 423) have a plurality of phase shifts of &thgr;(f)={&thgr;(f)1,2; &thgr;(f)2,3; . . . ; &thgr;(f)N−2,N−1}. A plurality of N−1 input phase shift circuits (431, 432 through 433) are coupled to the plurality of input nodes and provide input signals thereto. The plurality of input phase shift circuits (431, 432, . . . , 433) have a plurality of phase shifts of &PHgr;(f)={&PHgr;(f)1,2; &PHgr;(f)2,3; . . . ; &PHgr;(f)N−2,N−1}. To achieve the frequency selectivity of the current invention, &thgr;(f) is not equal to &PHgr;(f), so that output signals from the plurality of N amplifier stages (401, 402, 403, . . . , 404) are added with a frequency dependent phase relationship.
    • 与本发明的某些实施例一致的频率选择性差分放大器(400)具有共同驱动负载(410)的多个N个放大器级(401,402,403至404)。 多个N个放大器级(401,402,403,...,404)具有输入节点和输出节点。 多个N-1输出相移电路(421,422 ...,423)以使多个输出节点的输出信号相加的方式连接多个放大器级的输出节点, 多个输出相移电路(421,422 ...,423)中的负载(410)具有θ(f)= {θ(f))1,2的多个相移; theta(f)2,3; 。 。 。 ; theta(f)N-2,N-1}。 多个N-1输入相移电路(431,432至433)耦合到多个输入节点并向其输入信号。 多个输入相移电路(431,432 ...,433)具有Phi(f)= {Phi(f)1,2)的多个相移; Phi(f)2,3; 。 。 。 ; Phi(f)N-2,N-1}。 为了实现本发明的频率选择性,θ(f)不等于Phi(f),使得来自多个N个放大器级(401,402,403,...,404)的输出信号被加上 频率相关关系。
