兰姆达(lanbda,λ)二极管是具有双稳态开关特性的两端器件,可与其它器件一起容易地集成在同一芯片上,可望应用在保护、开关、振荡器及数字存储器电路里。负阻器件同单结晶体管与可控硅整流器一样,以前只限于在脉冲和开关电路里应用。然而,一个新的单块负阻器件——兰姆达二极管,在新的应用领域里,用途比较广,并且也简化了许多普通电路的设计。实际上兰姆达二极管是由一对互补耗尽型、结式场效应晶体管所组成的一个简单的两端器件。此二极管重要的特点是,它比普通的 Lambda (lanbda, λ) diodes are two-terminal devices with bistable switching characteristics that can easily be integrated on the same chip with other devices for applications in protection, switching, oscillators and digital memory circuits. Negative resistance devices with single-junction transistors and SCRs, previously only used in the pulse and switching circuits. However, a new monolithic negative resistance device, the lambda diode, is widely used in new applications and also simplifies the design of many common circuits. In fact, the Lambda diode is a simple, two-terminal device consisting of a pair of complementary depletion, junction field effect transistors. The important characteristic of this diode is that it is more than normal
