Over the past decade since its establishment in December 2012, Questyle has consistently incorporated founder Wang Fengshuo's groundbreaking "Current Mode Amplification" amplifier technology into all of its products. This unwavering commitment to innovation has earned Questyle numerous prestigious audio awards on a global scale.
“Current Mode Amplification,” a technique used in audio amplifiers based on current mode technology. This type of amplifier, known as a current mode audio amplifier, differs significantly from traditional voltage mode amplifiers in several key aspects. Here, I’ll elaborate on these aspects to provide a comprehensive understanding of current mode amplification.
Understanding Current Mode Amplification
Basic Concept: Current mode amplification represents a shift from the traditional voltage mode approach. In this method, the core amplification process occurs in the current domain, which involves processing the signal as a current rather than a voltage.
Circuitry and Components: These amplifiers utilize transistors (typically bipolar junction transistors) in a fully discrete architecture. The input and output remain in voltage mode, but the essential amplification happens in the current domain. This design ensures the amplifier operates constantly in a pure Class A state, known for high fidelity but less efficiency.
Differences from Voltage Mode Amplifiers: Unlike voltage mode amplifiers, which may include differential input stages and common emitter voltage amplification stages, current mode amplifiers have a distinct circuit structure. This unique structure allows for certain performance benefits, particularly in terms of speed and bandwidth.
Advantages: One of the main advantages of current mode amplification is the reduction of transient intermodulation distortion (TIMD), a common issue in traditional amplifiers. Moreover, these amplifiers can achieve extremely high bandwidth (up to 500 kHz at full power) and very low distortion levels (as low as 0.0002%). This performance challenges the limits of human auditory testing.
Versatility: Current mode amplifiers are versatile in their application, suitable for various power levels (ranging from 10mW to 2000W) and sizes (from a few square centimeters to professional-grade amplifier sizes).
Implication for Audio Quality: The low distortion and high bandwidth capabilities of current mode amplifiers suggest they can provide superior audio quality. They are particularly effective in delivering clear, accurate sound without the artifacts that often plague traditional amplifiers.
