Round 1

Reviewer 1 Report

This paper reports a MEMS resonator design, in which fabrication with foundry process and characterization is performed to to show suppression of capacitive feedthrough. The paper reports a comprehensive work and suitable for publication, upon carefully proofreading and addressing the minor errors below.

* Authors are asked to provide scanning electron micrographs as an addition to the optical images in Figure 6. 

* Improve sentence structures, reduce repetition of "this"

[line 40-42], .... this parasitic capacitive feedthrough between
the input and output ports becomes increasingly dominant and this electrical path through this capacitor results in a significant drop in SBR (signal to background ratio). This present a tremendous challenge to full electrical characterization of resonators in micron (and even more so for nano)

line 45 - resonate peak > resonant peak, resonance

line 67 - improve sentence .. "And meanwhile the devices were
68 fabricated in a commercial process which makes this method more cost-competitive" 

line 71 - insert loss > insertion loss

line 367 - figure 9 is erroneously written

"Figure 9. Last of all, in the case of DIDO setup, fully differential setup is adopted to achieve the"

Reviewer 2 Report

The authors present a Fully-Differential TPoS Resonators Based on Dual Interdigital Electrodes for Feedthrough Suppression. Overall, I believe it fits for the publication in Micromachines. MEMS resonator structure and performance are compelling. I would recommend to accept the manuscript without any changes.
