High Voltage Circuits

The LT5575 is an 800MHz to 2.7GHz direct conversion quadrature demodulator optimized for high linearity receiver applications. It is suitable for communications receivers where an RF signal is directly converted into I and Q baseband signals with a bandwidth...

Most operational amplifier circuits require a dual-polarity power supply - one having +V and -V. However, there are times when a DP supply simply isn't conveniently available. Single-polarity modifications to DP designs often achieve their effect by referencing the...

This is a variable high voltage DC power supply circuit that allows for customization of the output voltage ranging from 0 to 311V DC. It includes a current limit protection feature set at approximately 100 mA. The power MOSFET...

The high-speed peak detector utilizes a highly accurate, fast sample-and-hold (s/h) amplifier that is controlled by a high-speed comparator. The s/h amplifier retains the peak voltage until the comparator switches the amplifier to its sample mode to capture a...

This circuit is for a 2x2, 500W RMS stereo amplifier that is super-light and does not utilize a switching-mode power supply. The circuit diagram displays only one channel, while the power supply is designed to support both channels. The...

How to create a voltage multiplier using diodes and capacitors, capable of producing extremely high voltage. A voltage multiplier is a circuit that converts a lower AC or DC voltage into a higher DC voltage using a combination of capacitors...
