High voltage integrated capacitor and resistor for transimpedance amplifier
A recently granted patent (Publication Number: US11967610B2) discloses a method for manufacturing a transimpedance amplifier device. The method involves providing a semiconductor, forming a high voltage integrated capacitor with interdigitated fingers spaced at 0.3 µm or greater, and integrating a resistor to create a radio frequency (RF) filter along with the transimpedance amplifier. The device can handle high voltage signals between 60 and 90 volts and includes an avalanche photodiode (APD) for enhanced functionality. The APD is connected to the circuit node between the capacitor and resistor, contributing to the overall performance of the amplifier.
Furthermore, the patent details the construction of the transimpedance amplifier device, which includes a semiconductor substrate, an integrated capacitor, and an integrated resistor forming an RF filter. The device is designed to receive high voltage signals of 35 volts or greater, enhancing its versatility and applicability in various settings. Additionally, the inclusion of an APD, coupled with a can-shaped package and lens for fiber-optic signal transmission, showcases the comprehensive design of the transimpedance amplifier device. The integration of components like the APD and RF filter highlights the innovation and technical sophistication of the patented device, making it a valuable addition to the field of semiconductor manufacturing.
