提出了一种基于双轨差分逻辑的新型多值电流模式(MVCM)集成电路，其在低电源电压下具有高电流驱动能力，以实现完全自检电路和异步控制电路。在所提出的差分对电路（DPC）中，使用具有不同阈值电压的两个nMOS晶体管作为互补通路开关，使得即使在应用非码字输入（1, 1）时，DPC的输出也始终变得稳定，这使得可以使用MVCM电路设计自检电路。此外，可以自然地利用双轨MVCM电路技术来高效实现异步通信中的双色双轨数据传输方案。事实上，事实证明，自检乘法器和简单的异步控制电路的性能均优于相应的普通实现。
A new multiple-valued current-mode (MVCM) integrated circuit based on dual-rail differential logic, whose current-driving capability is high at a low supply voltage, is proposed to realize a totally self-checking circuit and an asynchronous-control circuit. Two nMOS transistors with different threshold voltages are used as complementary pass switches in the proposed differential-pair circuit (DPC), so that the outputs of the DPC always become stable even when non-code-word input (1, 1) are applied, which makes it possible to design a self-checking circuit by using the MVCM circuit. In addition, the dual-rail MVCM circuit technique can be naturally utilized for efficient realization of a two-color dual-rail data-transfer scheme in asynchronous communication. In fact, it is demonstrated that the performance of both a self-checking multiplier and a simple asynchronous control circuit is superior to that of the corresponding ordinary implementation.
