Analog Circuit Engineers - Contractors

We are looking for 2 types of circuit designers SerDes (10) HF frequency experience in nodes at 5nm or below with data rates of > 10 Gbps Serdes circuit experience is preferred but RF is also useful Data rates > 20 Gbps is preferred Precision LF (2-5) DC circuits such as voltage and current references, auto-zero comparators, voltage regulators etc. Must have implemented such circuits in nodes at 5nm or below
