【 摘 要 】

The paper introduces a novel memristive two-port element for an efficient construction of Radio Frequency (RF) single-pole double-throw (SPDT) switches, the so-called Two-Port Memistor (TPM). In comparison with the classical Widrow memistor whose resistance depends on the charge passing through the auxiliary terminal, the resistance of the TPM is governed by the controlling signal applied to the programming gate. It is demonstrated that the SPDT switch can be constructed via two TPMs such that the RF chokes providing DC references and capacitors for AC couplings are no longer necessary. Since the TPM-based switches provide elegant and much simpler circuit solutions than the currently developed memristive switches, this paper could stimulate the research towards manufacturing the TPM as a solid-state device.
