Multiple input Gates Waveform Generators to Produce Timing Signals Schmitt Waveform Generators can also be made using standard CMOS Logic NAND Gates connected to produce an inverter circuit. Here, two NAND gates are connected together to produce another type of RC relaxation oscillator circuit that will generate a square wave shaped output waveform as shown below. TTL logic ring oscillator Electrical Engineering Stack ... First reason would be if the Vout node is stuck at an intermediate voltage rather than perfect 0V or Vcc. Hence for that the ring oscillators generally have a enable signal and a nand gate instead of the first inverter to define the state. After some time the enable is switched OFF and the circuit will start with some good rail voltages at its nodes. NAND gate as an oscillator thescienceforum The NAND gate, when used in an oscillator circuit, is not functioning as a NAND gate at all. It is simply being used as an amplifying element. Practical circuits will often use things like feedback resistors to "bias" the gate into acting as a linear element, rather than as a digital element.

If you want to gate an inverter oscillator you can do so using a diode from V_control_in to oscillator IC input. When the diode conducts it swamps the feedback via VR1. If a low current enable line is required such that VR1 is too much of a load, drive another gate section and then use that gate to drive a diode disabler. EXPERIMENT 3: TTL AND CMOS CHARACTERISTICS TTL NAND gates. In the TTL family the number of transistors required to implement a NAND gate is less than that required to implement other gates such as AND, OR and NOR. Another factor in favor of NAND gates is the fact that any combinational logic function can be realized using just NAND gates.
