-The digitally-stepped attenuator is comprised of 2 transmission gates and an inverter, effectively creating a SPDT switch. One throw leads to a fixed resistor value, the other goes directly to next stage. There are a total of 4 of these stages, each comprising a slightly higher attenuation than the previous stage. They are controlled via 4 control lines. It is setup in a pseudo-differential configuration to attenuate both phases.

 ### Low-Noise Amplifier
 
 ![lna](docs/img/lna_layout.png)
 
-The LNA is a fully-differential common-source amplfier with active loads and a tail current mirror.

 ### Power Detector
 
 ![pd](docs/img/pd_layout.png)
-
-The power detector works by taking the differential input, creating a self-mixed DC current proportinal to the input power, and mirroring it and convering it into a voltage. This gets sampled by an off-chip ADC and MCU to drive the DSA.
