Much of the related body of DFT knowledge focuses on digital circuits while DFT for analog / mixed-signal circuits takes somewhat of a backseat.
22.
The strategic moves are meant to help Clare specialize on supplying analog semiconductors and mixed-signal circuits, for devices like mobile phones and hearing aides.
23.
The Zener antifuses can be made without additional manufacturing steps with most CMOS, BiCMOS and bipolar processes; hence their popularity in analog and mixed-signal circuits.
24.
The VLSI may include various types of circuits and systems, such as digital circuits and systems, analog circuits, as well as mixed-signal circuits and systems.
25.
Static relays offer the advantage of higher sensitivity than purely electromechanical relays, because power to operate output contacts is derived from a separate supply, not from the signal circuits.
26.
If the sloped-line segment is tangent to the real diode curve at the Q-point, this approximate circuit has the same small-signal circuit at the Q-point as the real diode.
27.
However, VHDL and Verilog share many of the same limitations : neither is suitable for analog or mixed-signal circuit simulation; neither possesses language constructs to describe recursively-generated logic structures.
28.
Small signal circuits are often deliberately designed to have very high gain, driving the signal far outside the linear range of the tube circuit, to deliberately generate large amounts of harmonic distortion.
29.
Another disadvantage was that in spite of the presence of the screen grids, the electron beam, modulated by the oscillator electrodes, still had to pass through the signal grid, and coupling of the oscillator into the signal circuit was inevitable.
30.
As a result of the Reciprocity Theorem the same loop will act as a receiver of high frequency noise and this will be coupled back into the signal circuits, with the potential to cause serious signal corruption and data loss.
