The versatile phase-locked loop (PLL) allows multiplication of a reference frequency with an operating frequency that ranges from “DC to daylight.” A PLL is overkill for some applications, however, ...

The circuit was designed to create a line preamplifier by acquiring the use of double triode tubes. The circuit comprises of three parts, the main preamplifier circuit with tubes, the input selector ...

High-precision timing generators and delay circuits form a critical backbone in modern electronics, enabling precise control and synchronisation in applications ranging from advanced instrumentation ...

Negative group delay circuits represent an innovative frontier in electronic engineering, wherein the output signal appears to precede its input. This seemingly paradoxical behaviour is achieved ...

This paper presents a technique that allows to preserve structure of a circuit according to a target technology during fault emulation in FPGA. The technique is not restricted to any target technology ...
