Wide-range level shifters play critical roles in ultralow-voltage circuits and systems. In this paper level shifter circuits that are capable of converting subthreshold to above threshold signal levels are presented. Level shifters are designed using current mirrors. The circuit has a distinctive current generation scheme using a logic error correction circuit that works by detecting the input ...

Evolutionary algorithms (EAs) are regularly used both for the solution of scheduling problems, and for the creation of digital circuit designs. This paper describes a unified approach, which mixes the creation of a sequential circuit, with the scheduling and binding of operations. This paper describes how Finite Impulse Response Primitive Operator Filters (FIR POFs) can be created so that they ...

Analog and RF circuit performance in single-chip transceivers can severely suffer from coupling of digital switching noise to the silicon substrate. To predict this performance degradation, a deeper understanding of the impact of substrate noise is absolutely necessary. Using measurements, this impact is studied as the cascade of an attenuation through the substrate from the source of substrate...

 The DSCH program is a logic editor and simulator designed by a research group under the leadership of E.Sicard, a professor of INSA of Toulouse . DSCH is used to validate the architecture of the logic circuit before the microelectronics design is started. DSCH provides a user-friendly environment for hierarchical logic design, and fast simulation with delay analysis, which allows the design a...

Rapid Single Flux Quantum (RSFQ) logic is a superconducting digital circuit technology that has emerged as a possible alternative to advanced semiconductor technologies for large scale ultra-high speed, very low power digital applications. Timing of RSFQ circuits at frequencies of tens to hundreds of gigahertz is a challenging and still unresolved problem. In many circuit topologies of current ...

1991 Abstract A logic simulator can prove the correctness of a digital circuit if it can be shown that only circuits fulllling the system speciication will produce a particular response to a sequence of simulation commands. This style of veriication has advantages over other proof methods in being readily automated and requiring less attention on the part of the user to the low-level details of...

Students studying undergraduate courses in digital electronics often lose interest in the subject, due to the short comings of learning tools that are commonly used to supplement such courses. Ideally learning tools increase student participation in the learning process and help in overcoming difficulties inherent to the subject. Comparisons have been drawn between the existing learning tools. ...

Full adder circuit is an essential component for designing of various digital systems. It is used for different applications such as Digital signal processor, microcontroller, microprocessor and data processing units. Due to scaling trends and portability of electronic devices there is a high demand and need for low power and high speed digital circuits with small silicon area. So, design and a...

Complexity of design and testing are the major obstacle for widespread use of asynchronous circuit in digital circuit design. Template based synthesis of asynchronous circuit is accepted as an effective way to decrease complexity of design of asynchronous circuit. One of the popular pre-designed templates that most synthesis tools use it to synthesis QDI asynchronous circuit is Pre-Charged Full...

–CMOL cell assignment Problem (BP) is a telecommunication problem. CMOL cell assignment problem is very complex due to its constraint. In CMOL cell digital circuits are mapped to the CMOL cell. Each component of digital circuit is assigned to a particular cell. For mapping a digital circuit to the CMOL cell we have to first convert the circuit in to NOR gate form. In this paper we have present ...
