The Active Current Supply it is a utility stage which provides a constant flow of current to the different blocks. A stable current source is important in order to improve linearity and noise rejection. With zero VGS the transistor enters in saturation region allowing a large current to flow through the JFET, so the current will increase.

As the current increases, a voltage drop will develop across the Zener, until the diode will be reversed biased.

The gate will become negatively biased with regards to the source, negative values of VGS will start to shut Q15 off. Once the drain-source voltage reaches a certain minimum value, enters saturation where IDS current is approximately constant.

As long as the Zener current Iz is between certain levels Izmin and Izmax called holding current, the voltage across the Zener diode VZ will be constantly working in the Voltage Regulation Area: The Zener diode stabilized voltage VZ drives an emitter follower Q14 loaded by a constant emitter resistor R9 sensing the load current.

The circuit operates as a constant current source: The external current mirror load of this current source is connected to the collector so that almost the same current flows through it and the emitter resistor. This topology is generally the best choice for an operational amplifier, it provides high input impedance, good voltage gain, common noise rejection as well as extra inputs for a summing feedback. To acquire real benefits from using an LTP input, the currents flowing through the differential transistors must be equalized.

A very effective way to do it is using a current mirror. The thermal coupling between both transistors is ideal since they share the same package.

There most important reasons to use a current mirror are to enhance the gain and the signal integrity: 1.

Signal integrity is improved because the current mirror gives equal quiescent current for each side of the LTP.

The JRC differential amplifier has a single-ended output, where the gain is the half if we compare it with a differential output circuit. The high gain voltage amplifier stage is the core of the power amplifier.

Its task is to amplify the low amplitude input signal to a suitable level. The is a micropower, precision voltage comparator with an on-chip voltage reference. The threshold is adjusted by the choice of two external resistors.

Voltage detection threshold is accurate to 1.

Supply current is extremely low 1. UCC : Power. Utilizing external P-channel MOSFETs provides the benefits of no loss-of-system ground in an overdischarge state, and protects the IC as well as battery cells from damage during an overcharge state. The Active Current Supply it is a utility stage which provides a constant flow of current to the different blocks.

A stable current source is important in order to improve linearity and noise rejection.
