摘要： A programmable gain amplifier (PGA) circuit includes a gain adjust circuit and a gain select circuit that are both coupled to an output of an amplifier. The gain select circuit completes feedback to the amplifier while the gain adjust circuit is arranged to boost or cut the gain of the gain selection circuit. The gain adjust circuit can be arranged as a trim adjustment to the overall gain of the PGA circuit, where a different trim adjustment can be mapped to each gain setting such as from a look-up table. In other example implementations, the PGA circuit can periodically switch between multiple gain settings using a modulation scheme such that the overall gain is blended between the various gain settings according to a duty cycle, pulse-width, or delta-sigma modulation, with a time averaging effect on the overall gain of the PGA circuit.

摘要： A gain-variable trans-impedance amplifier (TIA) in optical device is disclosed. The TIA has an improved dynamic range for receiving electrical signals and is configured to convert current signals from an avalanche photodiode (APD) to voltage signals. Aresistor element is between the input and output terminals of the TIA, wherein the resistance of the resistor element can regulate the resistance and/or impedance value of the TIA, and a switch determines or controls the resistance of the resistor element. When the power of an optical signal received by the APD is higher than a predetermined value, the resistance becomes smaller and the gain of the TIA becomes greater. When the power of the optical signal is lower than the predetermined value, the resistance becomes greater. The gain of the TIA is automatically adjusted on the basis of the intensity of received optical signals to obtain a greater dynamic operational range.

摘要： Various amplifier configurations having increased bandwidth, linearity, dynamic range, and less distortion are shown and disclosed. To increase bandwidth in a transimpedance amplifier, a replica circuit is created to replicate a degeneration resistance, or the resistance or value that relates to a feedback resistance. From the replica circuit, the replicated values are mirrored and processed to control a FET switch which modifies a degeneration resistance. The FET switch control signal is related to the feedback resistance and modifies the degeneration resistance to thereby maintain the product of the feedback resistance and the degeneration resistance as a constant. In another embodiment, a second switch controlled by an automatic gain control signal is established between a first stage amplifier and a second stage amplifier to improve dynamic range and bandwidth without degrading other amplifier specifications.

摘要：　演算増幅器において、オペアンプ（演算増幅段）１０の入出力間には、負帰還接続されたフィードバック容量３４と、そのフィードバック容量３４に直列に接続された抵抗素子（抵抗部）３０とを有する位相調整回路１００とが備えられる。また、前記オペアンプ１０の出力側には、負荷容量（負荷部）３２が接続されて前記オペアンプ１０からの出力信号によって駆動される。前記負荷容量３２、３３における容量値が大きくなり、当該演算増幅器の位相余裕が最適値に対して過剰になったときには、抵抗素子３０の抵抗値ＲＯを増加させて、演算増幅器の位相余裕を最適値の範囲に調整して高速なセトリング特性を実現する。従って、１段演算増幅器であっても適用可能な位相調整回路を提供し、更には演算増幅器自体の特性を高めて位相余裕を調整可能とすることによって、過渡応答が劣化した場合であっても高速なセトリング特性を実現することが可能となる。
