“…The crystal oscillator drive circuit designed is shown in Figure 3 The P3, P4, N2, and N3 tubes in the main part of the reference circuit form a current mirror structure that replicates each other. The N2 drain current can be expressed as formula (1) adjusting the resistor R2 to make the output branch a certain value; n is the ratio of N2 and N3 tubes.…”

Aiming at the disadvantage of high-power consumption and a long start-up time of the traditional Pearce driver circuit, a 32.768KHz crystal driver circuit is designed, which can effectively reduce power consumption and ensure a fast start. The simulation results show that, under the voltage of 1.1 V, the circuit vibration time is 0.5 ms, the output amplitude is about 250 mV, the static current is 48.6 nA, and the power consumption is 53.5nW. This drive circuit has the characteristics of a fast start, stable output, and low power consumption. It can be used as a clock input module in a digital-analog hybrid circuit.

“…Frequency scalable contour mode Scandium doped AlN on silicon TPoS resonator is designed as the frequency selective component of the oscillator demonstrated in this work due to their high-quality factor, low motional resistance, frequency scalability to few GHz and Quartz comparable ageing [1]. A third-order contour mode TPoS resonator is designed at 38.4 MHz as the reference clock to compare against performance of a 38.4 MHz industry standard off the shelf quartz crystal.…”

A 2.4 mW, 1ps RMS jitter temperature stable 38.4 MHz Thin Film Piezoelectric on Silicon (TPoS) MEMS based reference clocking chiplet implemented in Intel FinFET 22nm is presented as a viable traditional quartz crystal replacement. The TPoS full clock receiver comprises the TPoS resonator chiplet, pierce oscillator driver circuitry and the outer buffer converting the sinusoidal oscillation to a square digital clock. A 30ppm total frequency change across a temperature range from -40℃ to 120℃ is accomplished via a combination of passive compensation in the TPoS resonator structure and active temperature compensation using a fractional N Phase Locked Loop (PLL). Such competitive performance is achieved through a combination of the High-quality factor, low motional resistance, and the compensated composite structure of TPoS resonators along with design optimization of the 22FFL clock receiver circuitry.
