You should really try to keep after the example in the paper. Using a capacitor in parallel with a voltage source is not the same as with a current source -- the first simply shorts out the capacitor due to the internal, ideally null resistance, the other forms an integrator.
Looking at your pictures, it looks like you're using a ns scale, while the paper has ms scale. Also, it looks like you'e using a pulsed voltage for the battery(?) instead of a DC. I don't know where did you get the information about the control voltage, but it doesn't look like any of them should be conducting over a whole half-cycle.
So I gave it a try, guessing the values and timings (edit: I accidentally switched the control voltages, reversed them):
The current is a sine, the battery is simplified as a large valued capacitor, precharged to 2V.
I am using LTspice, you are using something different. It doesn't make sense to search for what I used in your library. Whatever voltage controlled switch your library has, that should be used. Additionally, I have plotted controlling waveforms, explained when the switch turns on and off, described the signal of the current source, I am sorry, but you have all you need to build the schematic. The same way you tried to build it from the picture in the pdf, the same way you can see the similarities between my schematic and the picture. I cannot draw things for you, I don't have what you have.
Still, I redid the schematic and I will describe it, maybe LTspice's interface is so unfamiliar to you that you cannot understand what is drawn (but then I don't understand how you managed to understand the picture in the .pdf):
I1 is a current source, set to be a sine waveform with
5uA (micro) amplitude and
50Hz frequency (or
C1 is a
15nF capacitor, with an additional flag which specifies that the initial voltage across it is zero (
S1 is a voltage controlled switch with the "on" resistance
1mOhm (milli), "off" resistance
1MegOhm (1e6), threshold voltage
Vh=0.5V hysteresis. The switch is turned "on" when the controlling voltage is greater than , or equal to
Vt+Vh, and turns off when it's less than, or equal to
V1 is the controlling voltage source for
S2 is a voltage controlled switch with the same parameters as
V2 is the controlling voltage source for

C2 is the equivalent of the battery, modeled as a large capacitor precharged at

V(pz) -- the voltage across

10ms period, and
1% duty-cycle, no delay;
