You can combine a carefully chosen op amp, a low-threshold P-channel MOSFET, and two feedback resistors to make a rectifier circuit with less forward drop than a diode (Figure 1). The rectified output ...
PIN diodes, which sandwich a lightly doped intrinsic (I) region between heavily doped P and N regions, are used extensively in RF and microwave applications. Common applications of PIN diodes are ...
A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...
Diodes has entered the precision low-voltage low-power op-amp fray with a dual-channel 8μV(typ) input offset voltage device consuming 12μA quiescent per amplifier. Diodes has entered the precision low ...
Frequency mixers are often implemented using a diode bridge or a Gilbert cell. Both types of mixers use a local oscillator (LO) to flip the polarity of the radio-frequency (RF) input. When the LO is ...
My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...
As part of our Op-Amp Challenge we’re seeing a wide diversity of entries showcasing the seemingly endless capabilities of these extremely versatile parts. Another one comes from [Joseph Thomas], who ...
PLANO, Texas--(BUSINESS WIRE)-- Diodes Incorporated (Diodes) (Nasdaq: DIOD) releases a high-precision operational amplifier (op amp) featuring input offset (VOS) stabilization for automotive signal ...
With a low input noise performance of only 8nV/vHz at 1kHz, the APX4558 dual channel op-amps from Diodes has a unity gain bandwidth of 3MHz. Two variants are being offered by Diodes, the commercial ...
