CMOS and BiCMOS Regenerative Logic Circuits

摘要: Schmitt triggers with standard CMOS logic circuits are described, first. Mathematical models for calculating basic parameters and their limits presented. Most of the chapter is dedicated to different solutions BiCMOS in monolithic integrated circuits. Two types inverters entirely topologies described. Also, voltage-controlled thresholds Beside inverters, NAND NOR analyzed. Basic circuit inverted trigger three pairs transistors. Expansion number inputs reached a similar way as It shown that voltage transfer characteristics depend, beside supply transistors, on logical circuits’ inputs. circuits, which hysteresis characteristic generated only through one input, also Analytic SPICE simulations used analysis static dynamic conditions work stability reliability. Areas reliability, influence technology electrical transistors Concerning field application, literature there (Zou et al, 2008, Al-Sarrawi, Katyal Lo 2010). In this chapter, fundamental applications digital – The author published most these (Dokic, 1983, Dokic 1984, 1996, Dokic, 1988). Today, some them 1984) treated conventional. term regenerative because every change state followed by process positive feedback. Owning that, has shape hysteresis, like trigger. That why commonly used. Unlike conventional where output level uniformly determined input value, certain extent, it not determined. fact, due area voltages between two thresholds, at depends, previous state. Due can be filters low frequency interferences. An example kind application given Fig.1. Whenever value signal passes threshold 撃脹 circuit, appears. Therefore, changes created noise transferred glitches. appear after amplitude greater than hysteresis.
