-This directory contains a mixed mode pll, combining
-ngspice and XSPICE circuit blocks.
-The pll consists of the following blocks:
-
-** voltage controlled oscillator:
-vco_sub.cir
-   7 stage ring oscillator with gain cells, CMOS devices
-or
-vco_sub_new.cir
-   vco made from code model d_osc, cntl_array/freq_array data
-   are gained by running test-vco.cir with vco_sub.cir
-
-** digital divider and frequency reference:
-pll-xspice.cir
-
-** phase frequency detector:
-f-p-det-d-sub.cir
-
-** loop filter:
-loop-filter.cir
-   switched current sources as charge pump, 2nd order
-   passive RC filter
-or
-loop-filter-2.cir
-   transistors as switches for charge pump, 2nd or 3rd
-   order passive RC filters
-
-** main simulation control:
-pll-xspice.cir
-
-Two test files are included:
-test-vco.cir simulates vco frequency versus control voltage
-test-f-p-det.cir simulates the phase frequency detector and the loop filter.
-
-The main building blocks are organised as subcircuits.
-
-main simulation control with three reference frequencies:
-pll-xspice-fstep.cir
-   simulates two steps of the reference in one simulation run
