Novatek is Russia's largest independent natural gas producer, and the country's second largest gas producer after state-controlled Gazprom. The US government imposed sanctions on the firm in July 2014 as Washington sought to increase pressure on the Kremlin for its perceived support of for separatist rebels in eastern Ukraine. The company was originally known as OAO FIK Novafininvest. Novatek is based in the Yamalo-Nenets Autonomous Region in West Siberia, and maintains a sales office in Moscow. The major shareholders of Novatek are Leonid Michelson, the CEO, with around 28% of the shares, Volga Group, the Luxembourg-based fund controlled by oil trader Gennady Timchenko, with 23% of shares and Gazprom with 10%. A 9.4% stake is owned by Gazprombank, while Novatek's CEO Leonid Mikhelson and Gennady Timchenko have an option to buy this stake. In 2013 Total SA increased its stake in Novatek to 16%. Wikipedia.

In the disclosure, an electrostatic discharge (ESD) protection circuit is coupled between a first power rail and a second power rail to discharge any ESD stress. The ESD protection circuit includes a detection circuit, a triggering circuit, and a dual silicon controlled rectifier (DSCR) device. When an ESD stresses is being applied to the first or second power rail, the detection circuit may first detect the ESD stresses and output a detection signal to the triggering circuit. The triggering circuit generates a triggering signal based on the detection signal and the polarity of the ESD stress. Then, the DSCR device is symmetrically triggered based on the triggering signal received at a common node between at least two transistors of the same type. The exemplary ESD protection circuit may be implemented in nanoscale manufactured integrated circuit and achieve good ESD robustness while maintaining low standby leakage current and relatively small silicon footprint.
