... Parallelizing n circuits can improve the SNR with a factor n [7]. Therefore, in proposed design by parallelizing the two PFD noise will reduce to 4db. Practically these PFD’s are closely placed on the die to avoid the correlation between noises produced by each PFD. B) Time shifted mode for Division ...

... To turn off the current source, we make the current equal to 0. We need to make it an open circuit here so the current is 0. To turn off the voltage source, we need to make it a short circuit. Look at the two 10 kΩ resistors. They are in parallel because they share the same pair of nodes. The two 10 ...

... It is in fact this model (where the internal noise is assumed to be created by the input) that we more typically use when considering the internal noise of an amplifier! To see why, recall that we can alternatively express the average SPD of noise in terms of a noise temperature T (in ...

... since I  VR R . Since I is maximized, the magnitude of both VC and VL are individually at maximum, although 180o out of phase with each other. When the frequency is not near the resonant frequency, the phasors representing VC, and VL do not cancel, so VR is less for a given Vs. It is convenient to ...


... The concepts investigated in this experiment are reactance, impedance, and resonance circuits. Many features of the scope will be used: including dual traces; differential inputs; and external triggering. Since this is the first experiment in which you have used the oscilloscope so a little extra ca ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
