The SHC615 is a complete subsystem for very fast and precise DC restoration, offset clamping, and low frequency hum suppression of wideband amplifiers or buffers. Designed to stabilize the performance of video signals, it can also be used as a sample/hold amplifier, high-speed integrator, or peak detector for nanosecond pulses. A wideband Operational Transconductance Amplifier (OTA) with a high-impedance cascode current source output and fast sampling comparator set a new standard for high-speed applications. Both can be used as stand-alone circuits or combined to form a more complex signal processing stage. The self-biased, bipolar OTA can be viewed as an ideal voltage-controlled current source and is
