I am trying to design a rectifier block for an inductive link. However, I am facing issues with transient simulation in Spectre, Cadence. As an example following is a simple resonant tank driven by an ac source with 50 ohm input impedance. The ac source is modeled by a sine voltage source with 50 ohm resistance in series. Series resonant tank consists of an ideal capacitor in series with an inductor (1 ohm parasitic resistance is included in the model). The circuit diagram is shown below:

The signal for different nodes are shown as follows:
VT("/GND!")
https://obrazki.elektroda.pl/11_1343785682.png
VT('net8')- Output of voltage source
https://obrazki.elektroda.pl/6_1343785783.png
VT("/net02")- At the top of inductor
https://obrazki.elektroda.pl/32_1343785855.png
Few details about the circuit:
1. The voltage source , amplitude = 1V, freq = 13.56 MHz
2. Following warnings during transient simulation.
Notice from spectre during topology check.
No connections to node `0'.
No DC path from node `net02' to ground, Gmin installed to provide path.
I am in a fix and can't figure out this basic circuit topology. any help in this matter will be appreciated.
Thanks,
