Plot 1 shows the Mokulab transfer function of the 10KOhm plus PZT.
Plot 2 shows the same same transfer function of this passive drive, but with a 1kOhm resistor and up to 100MHz.
Plot 3 again uses the 10kOhm resister, but includes the HV amplifier in the transfer function. It has a factor of 30 gain at DC.
For operations I suggest:
- Using a 100kOhm resistor, which makes a 37.5kHz pole.
- In addition, on D040105 (modified TTFSS for PMC), changing C51 to 3uF in series with a 1.3kOhm resistor will add a 3.4Hz:40.8Hz pole zero, moving the integration pole to 3.4Hz.
