Vacuum Tube Opamp Circuit -  Published In Glass Audio #3/1995 __ Contact: info @ forsselltech . com

Video multiplexer uses high-speed op Amps -  08/21/03  EDN-Design Ideas Video multiplexers route video from several sources to a single channel.  Low-end consumer products use CMOS analog switches and multiplexers, such as the 4066 and 4051.  Unfortunately, these devices have a series on-resistance that __ Circuit Design by Bruce Carter, Texas Instruments, Dallas, TX

Voltage Controlled Current Source with Ground Referred Input & Output -  A flying capacitor device such as the LTC1043 can produce a precision voltage differential over a wide common mode range.  Here it converts a ground referred input voltage directly to a differential voltage across a fixed resistor which then forces a precise current sourced at the circuit output. __ Linear Technology/Analog Devices App Note, Jun 21st 2011

Voltage-Based Controller for Switches -  Here’s a simple circuit for controlling four switches from a distance through just a pair of wires.In the circuit, the inverting inputs (pin 2) of operational amplifiers IC1 through IC4 are __ Electronics Projects for You

Water Level Controller-Cum-Motor Protector -  Many a time we forget to switch off the motor pushing water into the overhead tank (OHT) in our households.  As a result, water keeps overflowing until we notice the overflow __ Electronics Projects for You

Wide Common Mode Range 10x Gain Instrumentation Amplifier -  The LTC6090 is a high voltage precision operational amplifier.  The low noise, low bias current input stage is ideal for high gain configurations.  The LTC6090 has low input offset voltage, a rail-to-rail output stage, and can be run from a single 140V or split ±70V supplies __ Linear Technology/Analog Devices App Note, Feb 15th 2013

Wideband Digitally Programmable Gain Amplifier -  The LTC6910 is a CMOS programmable gain (from 0 to 64) amplifier.  The amplifiers provide for a differential input signal and for dc biasing the output into a precise voltage reference based level in a single supply design. __ Linear Technology/Analog Devices App Note, Mar 16th 2010

Wien Bridge Oscillator -  The opamp Wien-bridge oscillator provides a nice view into classic oscillator design using feedback analysis.  Feedback analysis reveals if your circuit is stable (well behaved) or unstable (may oscillate).  When designing amplifiers (especially high-speed ones), the trick is to avoid the conditions that make the circuit oscillate.  When designing oscillators, you strive to achieve those conditions in a predictable way.

Wireless Switch -  Normally, home appliances are controlled by means of switches, sensors, etc.  However, physical contact with switches may be dangerous if there is any shorting.  The circuit described here requires no physical contact __ Electronics Projects for You

Yield Accurate Absolute Values -  07/05/01  EDN-Design Ideas The circuit in Figure 1 delivers the absolute value of the input signal with an accuracy better than 10 ppm of the full-scale range.  The circuit has low zero-crossing error.  You can use it as an asynchronous demodulator, as a source __ Circuit Design by Marco Pisani, Istituto di Metrologia G Colonnetti, Turin, Italy
