The phase determines the oscillation frequency, and gain is a criterion for oscillation to exist. The four poles in the loop equation each contribute –45° phase shift accumulating the required total ...

See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...

In a power-supply topology for a computer system with a 12-V input and a 1-V, 20-A output, currents are high enough that duplicate power stages can be used to reduce stress and spread the thermal ...

The proposed shifter uses a half-mode substrate-integrated waveguide, with phase shifted in a via-pad-slot structure where a through via is attached to a pad surrounded by an annular slot. “The phase ...
