GATE EC PRACTICE TESTS : ANALOG CIRCUITS-PART-IV : LINEAR CIRCUITS AND POWER AMPLIFIERS


Well ! You must be waiting for this! Last test in this series, which is based on linear circuits and power amplifiers. MCQs included in the test are from previous GATE papers (1992 to 2004 - to be specific). Difficulty level is normal. No linked questions or common data questions. Few questions are figure based numerical problems and remaining are theory based questions.

POINTS YOU SHOULD ALSO KNOW :

**DIODES : Transition,diffusion capacitance,breakdown mechanisms
**DIODE CIRCUITS : Clippers, clampers, rectifiers (half,full,bridge with filter analysis)
**BJT/FET : biasing circuits, stability, small signal analysis and parameters
**AMPLIFIERS : multistage, effect of feedback with analysis,Miller's theorem, frequency response - cut-off frequencies and their dependency
**OP-AMPS : op-amp configurations, typical circuits, active filters, function generators,555 timers
**OSCILLATORS : Sinusoidal oscillators(Berk Hausen Criteria), LC(Hartley, Colpitts, Clapp),RC(Phase Shift, Wein Bridge),XTAL(Piezo)
