AN98-1 is a TI application note published in 2004. It introduces 18 circuit designs, including voltage controlled current source, signal source, conditioner and power circuit.
Published in November 2004, this document compiles eighteen specific circuit designs accumulated over time to address requirements for designing circuitry for specific purposes. The circuits are arranged into categories including voltage controlled current sources, stabilized oscillators, pulse generators, and frequency references.
The note details practical implementations such as a ground-referred voltage-controlled current source using differential amplifiers, an amplitude and frequency-stabilized 100Hz carrier oscillator for network telephones, and high-voltage micro-mirror display pulse generators. It also covers simple rise time and frequency reference circuits utilizing the LTC6905 oscillator.
The device achieves outputs over a continuous 17MHz to 170MHz range.
The rise time must be within 150ns into the 1500pF load.
