Low Voltage Bias Stabilizer
with Enable
Maintains Stable Bias Current in N−Type Discrete Bipolar Junction
and Field Effect
Transistors
Provides Stable Bias Using a Single Component Without Use of
Emitter Ballast and Bypass Components
Operates Over a Wide Range of Supply Voltages Down to 1.8 Vdc Reduces Bias Current Variation Due to Temperature and
Unit−to−Unit Parametric Changes
Consumes t 0.5 mW at VCC = 2.75 V Active High Enable is CMOS Compatible
This device provides a reference voltage and acts as a DC feedback element around an external discrete,
NPN BJT or N−Channel FET. It allows the external
transistor to have its emitter/source directly grounded and still operate with a stable collector/drain DC current. It is primarily intended to stabilize the bias of discrete RF stages operating from a low voltage regulated supply, but can also be used to stabilize the bias current of any linear stage in order to eliminate emitter/source byp...
