Abstract
Signal routing and EMIR requirements are causing increased demand for metal resources. The cost of metal resources is also an issue. The design and sign-off of on-chip drivers for driving signals from one chip location to another is complicated by requirements for power integrity and signal routing. This disclosure addresses routing resource bottlenecks and power requirements by introducing a low power driver useable in a high speed SERDES scheme. A voltage clipping high speed and low swing driver is disclosed. Threshold switching voltage of the transmitted signal is controlled by a process and temperature compensated biasing scheme. A reference voltage generation circuitry along with a simple receiver demonstrates the capability of this receiver. This transceiver scheme can be used on an on-chip or off-chip SERDES application to send/receive low speed signals serially. Use of this novel technique addresses the metal resource issue along with EMIR and SIPI requirements.
