# bandgap_bmr
A beta-multiplier reference design used to bias the bandgap op-amps.
Using matched PMOS the output will nominally be <img src="https://render.githubusercontent.com/render/math?math=5\ \mu A"> (<img src="https://render.githubusercontent.com/render/math?math=tt"> / <img src="https://render.githubusercontent.com/render/math?math=1.8\ V"> / <img src="https://render.githubusercontent.com/render/math?math=27\ ^{\circ} C">).
The layout is within the whole project layour GDS in `design/layout/amsat_txrs_ic.gds`.
More specs and test results to follow...
