Numerous circuit topologies have been proposed for divide-by-m injection-locked frequency dividers (ILFDs), most of which have been optimized for division by even numbers, especially divide-by-2. It has been more difficult to realize division by odd numbers, such as divide-by-3. This paper describes a CMOS injection locked frequency divider (ILFD) that can operate equally well in both divide-by-two...
Ge/Si avalanche photodiodes with record high gain-bandwidth and sensitivity for communication wavelength and high data rate, 10Gbps and 40Gbps, is demonstrated. These devices can be monolithically integrated with other silicon photonics components using CMOS technology.
A high-voltage operational amplifier (hvopamp) using dual-input floating-gate transistors for its feedback network is presented. The proposed hvopamp stabilizes the output DC voltage in the middle of its high-voltage power supply. Using floating-gate transistors eliminates the need for high-voltage resistor feedback networks. The integral nonlinearity (INL) of the hvopamp with floating gate feedback...
