Described in ISSCC 2017 Paper 5.3, the technique involves rapid and delicate adjustment of oscillator load capacitance to coax the crystal into life. The mechanical resonating parts of a crystal look ...

Figure 1 below shows the measurement result on one of the parallel resonant crystal connected to a pierce oscillator, where y-axis represents the output frequency deviation (in ppm) from rated ...

Primary design considerations for fundamental-mode oscillators using AT-cut crystals include load capacitance, negative resistance, startup time, frequency stability versus temperature ...
