Abstract

The discussions from the radiation experiments lead to a conclusion that the varactor of a conventional LC-oscillator is prone to Single-Event Effects due to the large collection area. These effects caused frequency steps since this charge moves to the loop filter of the PLL. In this chapter, an improved circuit is proposed which does not have this drawback. The idea is to avoid the charge collection in the varactors by biasing them in another way. The circuit topology is discussed, followed by heavy-ion experiments which are confirmed with TPA laser experiments.
