Using Op-Amps for Radio Frequency DesignQ1.Calculate the value of RG needed in order to produce the following output voltages (peak-to-peak): a. Vout = 5 voltsb. V out = 7.5 voltsc. V out = 10 voltsd. V out = 10.5 voltsAns V out = VRF +VINV V out=(IRF *RF ) +VINVWe connect RG from inverting input to ground to get more voltage, now the current Through RF is sum of currents through ROSC and RG.IRG=VINV/RGIOSC=VOSC/ROSCSo,IRF=IRG+IROSCTherefore we use this formula to find value of RG for given V outVOUT=RF*(VOSC/ROSC+VINV/RG)+VINVAs,VRES=VINV=1Vp-pVOSC=0.5Vp-pROSC=330?RF=1K?a) For V out =5vUsing the above mentioned formula for V out5=1000*((0.5/330)+(1/RG))+1(5-1)/1000=(0.5/330)+(1/RG)(4x10-3)-(0.5/330)=1/RGRG=402.43?b) For V out=7.5vUsing the above mentioned formula for V out7.5=1000*((0.5/330)+(1/RG)) ...
