Abstract :
A local oscillator for the Linear Ion Trap Standard (LITS) has been designed and tested It uses a Time-to-Analogue (TAC) converter to achieve the required resolution and low noise. The TAC has an instantaneous resolution of 23 bits and an accumulative resolution of approximately 34 bits. The noise analysis, circuit details and block diagram are given, as well as the performance of the loop
