AMP55 HiFi Bluetooth Desktop Mini Audio Power Amplifier 220V Translinear Current Mode Amplifier
Description:
- Adopting trans-conductance linear current mode technology with high resolution, wide sound field, accurate positioning, transparent background, objective and rational sense of speed, clear vocal and instrument contours, sound notes in place and outstanding "unwavering" fixation, strong control in mid to low frequencies, neutral and durable tone.
Translinear Current Amplifier:
- Current mode circuits are circuits that can effectively transmit, amplify, and process current signals. In current mode circuits, current is used as a variable to analyze and calibrate the circuit.
- The corresponding voltage mode circuit is a circuit that focuses on transmitting, amplifying, and processing voltage signals, and analyzes and calibrates the circuit with voltage as a variable.
- The theory and technology of current mode have developed rapidly in recent years, with its main characteristics being high-speed transmission and very small distortion. For a long time, people have been accustomed to processing voltage signals while neglecting the processing of current signals.
- In practice, many devices have current transmission functions, such as BJT and FET, where the transmission signal is a current quantity. So when processing signals, it is not necessary to convert them into voltage. For these devices, using current mode processing method is simpler and more convenient.
- The main difference between current mode and voltage mode circuits lies in the input and output impedance. Firstly, an ideal voltage amplifier requires an infinite input impedance and zero output impedance. This requirement is beneficial for voltage signal transmission. For an ideal current amplifier, the input impedance is zero and the output impedance is infinite, which is the only way to facilitate the transmission of current signals.
