The circuit below is an oscillator. 1) Find the loop gain I Call of the oscillator 2) Apply Barkbrisen Criteria to find: The expropion of the frequency of socillation of the output V. at a function of circuit revivton and capacitor, and I) Design the oke illalor to produce a surewave with a frequency of 4He 1) Simulate you design using Moldsin solving old jive screenshot of your violation res and cheun ted in Molina. Give a memine of be bequency of the output soul. 3) Propose a modification to the circuit to limn the anglinde of the curgus " Sinnilate your decals miing Multisun and adjust your amplinude coultel mechanism to have output with a TiLD not premier them 1 20% and amplimade in the tripe ovpp to SVpp. This me what we need a dippel with a fined peak-to-peak amplitude which is not less than CV and Brewer chan TV Show your s nulation rewas and the THD of your spal
