  2. Synthetic biological circuit - Wikipedia

    en.wikipedia.org/wiki/Synthetic_biological_circuit

    Synthetic biological circuits are an application of synthetic biology where biological parts inside a cell are designed to perform logical functions mimicking those observed in electronic circuits. Typically, these circuits are categorized as either genetic circuits , RNA circuits , or protein circuits , depending on the types of biomolecule ...

  3. Electronic oscillator - Wikipedia

    en.wikipedia.org/wiki/Electronic_oscillator

    Simple relaxation oscillator made by feeding back an inverting Schmitt trigger's output voltage through a RC network to its input.. An electronic oscillator is an electronic circuit that produces a periodic, oscillating or alternating current (AC) signal, usually a sine wave, square wave or a triangle wave, [1] [2] [3] powered by a direct current (DC) source.

  4. RC oscillator - Wikipedia

    en.wikipedia.org/wiki/RC_oscillator

    Another common design is the "Twin-T" oscillator as it uses two "T" RC circuits operated in parallel. One circuit is an R-C-R "T" which acts as a low-pass filter. The second circuit is a C-R-C "T" which operates as a high-pass filter. Together, these circuits form a bridge which is tuned at the desired frequency of oscillation.

  5. Oscillation - Wikipedia

    en.wikipedia.org/wiki/Oscillation

    Phase portrait of damped oscillator, with increasing damping strength. All real-world oscillator systems are thermodynamically irreversible. This means there are dissipative processes such as friction or electrical resistance which continually convert some of the energy stored in the oscillator into heat in the environment. This is called damping.

  6. Synthetic biology - Wikipedia

    en.wikipedia.org/wiki/Synthetic_biology

    The creation of whole new signalling pathways, containing numerous genes and regulatory components (such as an oscillator circuit to initiate the periodic production of green fluorescent protein (GFP) in mammalian cells), is known as bioengineering as part of synthetic biology. [38]

  7. Phase-shift oscillator - Wikipedia

    en.wikipedia.org/wiki/Phase-shift_oscillator

    A phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output. It consists of an inverting amplifier element such as a transistor or op amp with its output fed back to its input through a phase-shift network consisting of resistors and capacitors in a ladder network .

  8. Butler oscillator - Wikipedia

    en.wikipedia.org/wiki/Butler_oscillator

    The classic Butler oscillator circuit is a two-stage circuit with two non-inverting stages, a grounded base stage and an emitter follower. [5] The crystal is inserted in series in the overall feedback path. [5] AC equivalent circuit. The more common modern form of the circuit uses just the emitter follower stage.

  9. Multivibrator - Wikipedia

    en.wikipedia.org/wiki/Multivibrator

    A vacuum tube Abraham-Bloch multivibrator oscillator, France, 1920 (small box, left).Its harmonics are being used to calibrate a wavemeter (center).. The first multivibrator circuit, the classic astable multivibrator oscillator (also called a plate-coupled multivibrator) was first described by Henri Abraham and Eugene Bloch in Publication 27 of the French Ministère de la Guerre, and in ...
