5GB/s radiation hard low power point to point serial link

The presented system is a high-speed radiation hardened by design link technology. The link operates at 5Gbps, and occupies a very small area (50μ×200μ+pad for each TX and RX) in its 130nm implementation. The on the wire encoding is in the form of pulses, dramatically simplifying the data recovery process, allowing flexibility in the transmitter and receiver design. Neither the transmitter nor the receiver uses a high-speed clock, instead small state machines are used to handle the transmit and receive functions.
