271 : Analog Test Circuit ITS 2

Author: A. N Irfansyah, Raditya Eka, Yohanes Stefanus

Description: PLL parts (VCO and phase detector)

Clock: 0 Hz

This tinytapeout submission consists of:

A VCO based on transmission gates with additional on-chip capacitors to further linearize the response.
A phase detector and VCO to form parts of a PLL.

Pinouts:

Analog pins:

ua[0] - VCO #1 output

ua[1] - VCO#1 VCONT- / Phase Detector (PLL) ref

ua[2] - VCO#1 VCONT+ / Phase Detector (PLL) input / PLL feedback

ua[3] - PLL VCO output

ua[4] - PLL Filter (n)

ua[5] - PLL Filter (p)

To test, typical experimental setup to test pll, or vco, would be required.
