1 parametric amplifiers 1.1 introduction 1.2 mathematical equation 1.3 advantages 1.4 other relevant mathematical results parametric amplifiers introduction a parametric amplifier implemented mixer. mixer s gain shows in output amplifier gain. input weak signal mixed strong local oscillator signal, , resultant strong output used in ensuing receiver stages. parametric amplifiers operate changing parameter of amplifier. intuitively, can understood follows, variable capacitor based amplifier. q [charge in capacitor] = c x v therefore v [voltage across capacitor] = q/c knowing above, if capacitor charged until voltage equals sampled voltage of incoming weak signal, , if capacitor s capacitance reduced (say, manually moving plates further apart), voltage across capacitor increase. in way, voltage of weak signal amplified. if capacitor varicap diode, moving plates can done applying time-varying dc voltage varicap diode. driving voltage comes oscillator — called pump . the resulting output...
