Working Principle

The PEMH14,115 is a pre-biased amplifier that operates in the common emitter configuration. This device is designed to provide high gain with low power consumption and low noise. It is comprised of four bipolar junction transistors (BJT’s) that are connected in a common emitter configuration. In this configuration, the base-collector junctions of the transistors are reverse-biased, while the base-emitter junctions are forward-biased. This is known as a voltage pre-biased array.

When a signal is applied to the input of the PEMH14,115, the signal current passes through the circuit and is amplified by the transistors. The signal is then output from the device’s collector. The signal is amplified by a factor of the current gain (beta) of the transistors. The gain of the device depends on the specific parameters of the transistors, such as their Beta and current amplification factor (CMRR). The gain of the device can be adjusted by changing the bias voltage of the transistors.

The PEMH14,115 is an ideal solution for applications requiring high gain, low power consumption, and low noise. Its pre-biased configuration allows for easy implementation and eliminates the need for external components, resulting in a compact and cost-effective solution.
