This circuit/sensor uses 81pF as the resonant cap. Thus we can have substantial input capacity of the amplifier (several PF) without serious upset to the energy storage and tuning. To avoid dampening, the interface needs to have impedance >> the reactance of 1Henry at 17,000 Hertz, which is about 100,000 ohms.
First, lets bias that sensor to VDD/2 approximately.
Use two 1 MegOhm resistors in series, running from VDD to Ground. Place 100pF cap from the midpoint to your sensor. We now have VDD/2 voltage plus your sensor. The interface resistance is 1M || 1M or 500,000 ohms, which supports a Q=5 for your sensor. That is about what I observe (the rate of buildup of the voltage) in your simulation. You can use 3.3M or 10Meg ohms (two in series) if you wish.
Get yourself some opamp that uses FET (CMOS) technology. Read the datasheet, or examine the INPUT BIAS CURRENT for room temperature operation. The input bias current will be picoamps ( << 1 nanoAmp, may be the spec value) for a CMOS opamp. Such low input bias currents ensure the VDD/2 voltage divider will continue to define the DC input voltage.
Ensure the opamp works on 0/+5 volt rails. Because of how this circuit (to be detailed below) operates, you do not require rail_rail input nor rail_rail output, but such performance will not degrade the performance. Do not use micropower (1uA Iddq) opamps; the speed will be way too slow.
Connect the Vin+ of the opamp to that 1Megohm + 1Megohm midpoint.
From Vin- of the opamp to Ground, install a 1Kohm in series with 0.1uF cap. This series network is DC_blocking, with negligible effect at 17,000Hz.
[ hmmmm the time constant of R * C = 1e+3 * 1e-7 = 1e-4 or 100uSec, which is 1,600 Hertz, so yes has negligible effect.]
From Vin- to Vout of the opamp, install the Feedback network --- use (initially) a 100,000 ohm resistor. Even if the opamp has only 1MHz UGBW, you should observe a gain of 1,000,000 / 17,000 = 55X stronger signal on the opamp output.
An opamp with UGBW higher, such as 3MHz or 10MHz, should provide 100X gain (40dB).
And the output will be biased at VDD/2, so first verify the output DC is (near) VDD/2, then switch the scope to AC coupling, and verify the expected gain.
I've suggested the 1Kohm and 100Kohm resistors be used to set the gain, because high values will allow phase_shifts in the opamp's feedback path, which may cause ringing or oscillation. You don't need that bother.
