Analog and RF Testchip on Skywaters 130nm Technology.

In this tapeout, we are planning to achieve the following:

  • 5 Transistor OTA with trimming resistors to adjust bias. [Completed with Layout, without the trimming resistor]
  • LDO [Schematic is complete, no layout currently]
  • VCO at 2.45GHz for BT, Wifi applications [Tentative plan and in progress]

LDO Design

  • Input voltage is 1.8V
  • Will add the specs later.

Schedule and timeline:

Monday December 7th, 2020

  • Complete the layout of trimming resistor for biasing of the 5 Transistor OTA

Thursday December 10th, 2020

  • Complete the LDO layout.

Thursday December 17th, 2020

  • Add a second stage for the OTA and have double stage OTA to achieve higher gain.
