21Current source — Figure 1: An ideal current source, I, driving a resistor, R, and creating a voltage V A current source is an electrical or electronic device that delivers or absorbs electric current. A current source is the dual of a voltage source. The term… …
22Linear regulator — In electronics, a linear regulator is a voltage regulator based on an active device (such as a bipolar junction transistor, field effect transistor or vacuum tube) operating in its linear region (in contrast, a switching regulator is based on a… …
23Common base — Figure 1: Basic NPN common base circuit (neglecting biasing details). In electronics, a common base (also known as grounded base) amplifier is one of three basic single stage bipolar junction transistor (BJT) amplifier topologies, typically used… …
24Common collector — Figure 1: Basic NPN common collector circuit (neglecting biasing details). In electronics, a common collector amplifier (also known as an emitter follower or BJT voltage follower) is one of three basic single stage bipolar junction transistor… …
25Cascode — The cascode is a two stage amplifier composed of a transconductance amplifier followed by a current buffer. Compared to a single amplifier stage, this combination may have one or more of the following advantages: higher input output isolation,… …
26CMOS — For other uses, see CMOS (disambiguation). CMOS inverter (NOT logic gate) Complementary metal–oxide–semiconductor (CMOS) (   …
27Negative feedback amplifier — Figure 1: Ideal negative feedback model A negative feedback amplifier (or more commonly simply a feedback amplifier) is an amplifier which combines a fraction of the output with the input so that a negative feedback opposes the original signal.… …
28Buffer amplifier — A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another. Two main types of buffer exist: the voltage buffer and the current buffer. Figure 1: Top: Ideal voltage… …
29Voltage-to-current converter — Introduction For a variety of reasons, in low voltage electronics, voltage is a more frequently used data carrier. Thus electronic devices tend to be labeled with voltage inputs and outputs. However some devices are labeled in terms of current… …
30Voltage regulator — A popular three pin 12 V DC voltage regulator IC. A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level. A voltage regulator may be a simple feed forward design or may include negative feedback …
