From the current journal in solid state circuit and circuit and systems literature, it is well known that the Gilbert Modulator and a modification of its core circuit are considered to be the good candidate for amplitude modulator but for the frequency modulator there is no derived formula from the circuit diagram that it looks similar or comparable with the ideal frequency modulator formula. It may be important to synthesize the frequency modulator circuit from the ideal frequency modulation formulas. Instead of drawing the circuit diagram and measured its time domain waveform from the oscilloscope so that it can be compared with the ideal modulator waveform in the time domain.
Aims and Scope:
Request novel circuit diagram and block diagram of modulator and demodulator (PLL or Costas Loops)
Request how to analyze the circuit diagram of the modulator and demodulator
Show the simulation results
Show the experimental results
Review and compare, comments the modulator and demodulators from IEEE Journal of solid state circuit and circuit and system
Compute the specifications of the modulator and demodulator by a figure of merit of the modulator
