A transimpedence amplifer (TIA) includes a photo-detector, and the TIA is formed by a first TIA inverter and a second TIA inverter. The first TIA inverter has an input from a cathode side of the photo-detector and the second inverter has an input from an anode side of the photo-detector. A replica TIA is formed by two replica inverters, coupled to a respective input to a first operational amplifier and a second operational amplifier. The first operational amplifier and the second operational amplifier have a feedback configuration for respectively regulating a set voltage level at the cathode side of the photo-detector input of the first inverter and at the anode side of the photo-detector input of the second inverter.

摘要： A method and circuit are provided for implementing an enhanced bias configuration for CMOS inverter based optical Transimpedance Amplifiers (TIAs). An operational amplifier is provided in a feedback configuration that forces an input of the CMOS inverter to a set voltage level by regulation of the inverter power supply. A photo-detector sees a more stable bias voltage, and the responsivity of the photo-detector is more robust and the TIA has improved performance across process corners.

摘要： A circuit component comprises a row of transistors. The row may contain a first active FET with a source region and a drain region. The row may also contain a first active dummy FET that shares the source region and that also has a diffusion region. The row may also contain a second active FET and a second active dummy FET, positioned such that the active dummy FETs are located between the active FETs on the row. The row may also have an end positioned such that the first active dummy FET is between the end and the first active FET. A supply of current may be electrically connected to the source diffusion regions. A load region may be electrically connected to the drain region. The first active FET and the first active dummy FET may have gates that share a voltage source or that have their own voltage source.
