针对低能量流水线系统，提出了一种多值电流模式(MVCM)电路中的静态电流源控制技术。嵌入在每个流水线级中的电流控制块产生电流控制信号，这根据给定的条件最小化了电流量。这种电流源控制技术的使用使得在保持工作频率的同时降低功耗成为可能。通过在0.13um工艺下的HSPICE仿真，验证了该方法在流水线MVCM乘法器中的有效性。与传统的MVCM电路相比，采用该技术的MVCM电路在工作频率为100 MHz时降低了65.1%的功耗，在500 MHz时以6.88%的面积开销降低了26.5%的功耗。
A static current-source control technique in a multiple-valued current-mode (MVCM) circuit is proposed for a low-energy pipelined system. A current-control block embedded in each pipeline stage generates current control signals, which minimizes the amount of current flows depending on a given condition. The use of this current-source control technique makes it possible to reduce the power dissipation with maintaining the operating frequency. The efficiency of the proposed technique in a pipelined MVCM multiplier is confirmed by using HSPICE simulation under 0.13um CMOS technology. The MVCM circuit using the proposed technique achieves 65.1% power reduction compared with a conventional MVCM implementation at the operating frequency of 100MHz and 26.5% reduction at 500MHz with 6.88% area overhead.
