final gds & drc results
Design of an LVDS receiver in Skywater 130nm. The receiver architecture consists of a biasing stage followed by two amplification stages—the simulated maximum frequency of 1.5Gs at 1.8V, TT corner & 25C.
Submodules:
Biasing Stage – AC coupled with common-mode biasing of 1.2V
CML Stage – Amplification stage with a gain of 5
Differential Stage – Gain of ~8
7 stage RO with enable
Designed with Skywater standard cells library. AND gate followed by 7 smallest inverters
5 stages of differential delay cells. Delay cell consists of symmetric loads
Submodule:
Self bias generator with startup circuit
Linear Class AB power amplifier. On-chip inductor is designed as a test structure by using top metal layer. Actual inductance & Q factor is unknown
Differential input single ended Folded Cascode Opamp; 1Mhz unity gain frequency, 60 degree phase margin & a gain of 79dB
