Constant current sources for audio amplifiers Abstract. Constant current sources are basic building blocks of almost every analog audio amplifier. There are countless circuits and each has its own unique properties. In this article I will compare a small selection of different variants with each other in order to identify their advantages. I will use the best ones for my next audio …

The source can supply low noise constant current starting from as low as 1 μA to a few tens of mA with a high voltage compliance limit of around 20 Volts. The constant current source has several stages which can work in a standalone manner or together to supply the desired value of load current.

Reference Constant Current Source for DIY Audio and beyond (and anything else that requires the really good CCS :)) - I have this project under development. The "magic" CCS promises to have quite outstanding parameters: I nominal as from tens of micro-Amperes up to 400 mA (subject to some 50W power limit)

Make a constant current source coming from V+ (positive supply rail) using two PNP transistors, or two diodes and one PNP with an emitter resistor. This current is feeding a current mirror, using figure 5 in CCS and mirrors alternatives, in an earlier post above. Current mirror is two NPN attached to negative rail.

Active constant current sources/sinks are becoming more common, but inductors were the traditional AC approximations to constant current sources/sinks, the main audio example being the choke in a choke input power supply (source) or the primary inductance of an output transformer (sink).

1.0 - The Perfect Current Source. A perfect current source can be constructed very simply, requiring only an infinite voltage and an infinite resistance. Unfortunately, this will also provide an infinite current (which will be infinitely constant), but is (infinitely?) excessive for an infinite number of applications.

Q6 and Q7 form a constant current source of about 10.3mA at Q7's Collector. Q5 is simply a relative mirror of 7mA using the Base voltage of Q7 as its reference. Q5 has nothing to do with the Q6/Q7 CC source.

diyAudio Tube Constant Current Source Board Project. The diyAudio.com CCS PCB is an array of circuit boards for constructing various constant cur-. rent sources/sinks for prototypes or as modules in a final design. The topology of all the cir-. cuits is the same- a cascode bipolar with an LED reference.
