Y yy.toh New Member Mar 9, 2011 #1 I have simulate a hartley oscillator at 27Mhz, its ouput is peak to peak 4nV. I need 6V peak to peak. Any idea how to amplify it? Last edited: Mar 9, 2011

Now I wonder where is the location of the output. at base before the coupling capacitor: V peak to peak 500mV I peak to peak 100mA at base after the coupling capacitor: V peak to peak 40uV I peak to peak 8uA at collector: V peak to peak 300nV I peak to peak 300nA The values at collector is smaller than the base, i donno why?
