In signal processing, when describing a periodic function in the time domain, the DC bias, DC component, DC offset, or DC coefficient is the mean amplitude of the waveform. If the mean amplitude is zero, there is no DC bias. A waveform with no DC bias is known as a DC balanced or DC free waveform. Ver mais The term originates in electronics, where DC refers to a direct current voltage. In contrast, various other non-DC frequencies are analogous to superimposed alternating current (AC) voltages or currents, … Ver mais • Phantom power • Root-mean-square amplitude • Root-mean-square voltage • Ver mais In the design of electronic amplifier circuits, every active device has biasing to set its operating point, the steady state current and voltage on the device when no signal is applied.

It's easiest to make integrated circuits using just one kind of transistor. Traditional op-amps are made entirely of bipolar transistors. (Plus some passive components.) The first really popular IC op-amp was the µA741, introduced way back in 1968, yet still available today.

WebThis report examines the behaviors of the input offset voltage over temperature for two amplifiers. One amplifier is a low-speed op amp with a small input offset voltage (µV). The second amplifier is a high-speed op amp with a large input offset voltage (mV). The same nulling-offset approach is taken for both op amps.
