Hi, I am trying to build a clock for a microcomputer using discrete components, the less components the better.
An oscillator that worked is the attached one, but the output signal swing was about 3.5Vpp when loaded by an external 74LS74 flip flop and also a 74LS165, which seems is not enough to clock the 165.
The ceramic resonator and the 100nF capacitor cannot be changed and the 100nF is connected to the ground, so I do not want to change that (so as to not modify the micro PCB.
What are my options to bring the swing close to rail to rail?
