A quadrature modulator based scheme for frequency hopping applications

In this study a new frequency hopping scheme which relies on digital up-conversion of baseband data is proposed. Since the frequency of the local oscillator is kept constant and hopping is achieved in the baseband, the time required for the frequency jump is independent of...

FinFET based 4-BIT input XOR/XNOR logic circuit

In this paper a structure for direct 4-BIT XOR/XNOR logic cell is proposed. This structure is proposed using pass transistor logic with FinFETs. This structure has less delay for the reason that its critical path consists of a minimum number of transistors. The basic adva...

Logboat — A simulation framework enabling CAN security assessments

Traditionally, fieldbus networks are operated in closed environments, where all communication nodes are assumed to be trustworthy. Therefore, the corresponding standards do not consider any security requirements. New technology trends, such as the upcoming Internet of Things (IoT), demand an inte...

Implementation of constant phase elements using low-Q band-pass and band-reject filtering sections

This paper briefly describes possibility to use band-pass and notch filters with low quality factors for straightforward synthesis of the so-called constant phase elements. These filters connected in cascade can form desired alternation of transfer function zeroes and poles. Using proposed a...
