VIC-5 phase-locked loop

With these chokes and this cell, where is the resonance — and can this PLL reach it, hold it, and build the rise inside each gate?

Loading a circuit fills the slots; change any of them afterwards and the result is your variation on it. All saved circuits.

The parts

The cell

The water capacitor the loop has to find the resonance of. About this part.

Water optional

What is in the cell.

Charging choke

The choke on the positive side.

Its core optional

What the charging choke is wound on.

Blocking choke

The choke on the return side.

Its core optional

What the blocking choke is wound on.

Transformer optional

Between the VCO's driver and the chokes, if there is one.

The drive

x VCO centre frequency

kHz

Where the VCO sits with no correction — the middle of its range.

V Drive amplitude

The peak voltage applied across the loop — after the transformer, if there is one.

v VCO gain

Hertz per volt of control voltage.

d Phase detector gain

Volts per radian of phase error.

R₁ Filter resistor R₁

kΩ

The lag-lead filter's series resistor.

R₂ Filter resistor R₂

kΩ

The resistor in series with the filter capacitor.

C₁ Filter capacitor

µF

The filter capacitor.

g Gate frequency

The slow gate switching the locked drive on and off.

G Gate duty

How much of each gate period the drive is let through.

c Choke arrangement

Separate, or on one core with fields aiding or opposing.

k Coupling coefficient

How much of one choke's flux threads the other.

From the parts

Every number handed to the simulation that you did not type, and where it came from. Each derivation that ran a calculation links to that calculation's page with these numbers in, so it can be checked alone.

R Series resistance 0.1 Ω

Series resistance, added up: Nine cells in series (Russian build) 0.1 Ω. Wiring and connections are not counted.
C Cell capacitance 1.037 nF

Nine cells in series (Russian build), as recorded on the part.
C Cell capacitance 115.2 pF

9 such cells in series. The array calculation's inductance is a placeholder for its resonance figure; the capacitance does not depend on it.

Multi-cell array — 2 notes on that page

No water chosen, so the cell is taken as full of distilled water at 20 °C. Pick a water to change that.
