Latest Patents

Among his latest innovations is the H-bridge integrated laser driver. This cutting-edge technology optimizes power dissipation, impedance matching, low-swing, and high-swing reliability for electro-absorption modulated laser (EML) and directly modulated laser diode (DML) applications. The innovative laser driver incorporates a retimer that converts low-speed parallel data to a high-speed serial bit stream, alongside an inverted representation of the data. Additionally, it includes an M-bit PMOS DAC for receiving a buffered bit stream and an N-bit NMOS DAC synchronized with it. A protective device is strategically placed between the two DACs, while DC level-shifting predriver arrays ensure effective signal management. This technology is especially beneficial when integrated on a CMOS communication chip.

Another noteworthy patent is the high-speed DC shifting predriver. This involves an input port designed for coupling with a serial data stream and an inverting output amplifier that enhances signal clarity. By employing a weak feedback inverter, this predriver achieves a remarkable DC shift of up to 3V, all while minimizing intersymbol interference, thus accommodating data rates from 10 GS/s to an impressive 28 GS/s or higher.
