Essential Circuits for System Design
- Analog Signal conditioning circuits: Buffering, scaling, level translation, filtering and applications
- Analog math circuits - arithmetic circuits, log circuits, trigonometric circuits and applications
- Timer circuits, pulse width modulation circuits, P, PI and PID controller circuits, protection circuits, base and gate drive circuits for power transistors, MOSFETs and IGBTs, relay and contactor drive circuits.
- Power supply circuits: Board level power supply circuits to generate +/-12V, 5V, 3.3V, 1.8V. Linear regulators, low drop out regulators, charge pumps, switched mode power converters.
- Interfacing circuits: A to D, D to A, A to A and D to D interfaces, serial and parallel DACs, sampling, RS-232, USB, I2C, LCD, serial memory, SPI, wireless, Ethernet, RFID, SD card, SIM card, GPS interfaces.
- Digital circuit essentials: Digital filters, moving average, numeric formats, scaling, normalizing, arithmetic, log, exponential, square root, cube root, hypotenuse, sine, 3 phase waves, PWM etc.
- 6 sessions for Analog signal conditioning circuits
- 4 sessions for power supply circuits
- 8 sessions for interfacing circuits.
- For interfacing circuits an 8 - bit microcontroller with DIP package (probably in ATmega series) can be used so that students can rig up the circuits during lab sessions on general purpose boards.
