- Single Op Amp Achieves Double-Hysteresis-Transfer CharacteristicEncarna García Herminio Martinez Juan GámizIn process-control applications requiring discontinuous controllers, the most elementary choice is a two-position-mode or on/off controller. A typical example of such a controller is a space heater. If the temperature drops below a setpoint, the heater turns on, and, if the...13-09-2022
- JFETs Offer LC Oscillators with Few ComponentsBy using JFETs in unusual configurations, you can design simple, high-frequency LC oscillators with few passive components. The structure for implementing the amplifier stage comprises a JFET transistor that you configure as a common drain...21-10-2021
- Soft-Limiter Circuit Forms Basis of Simple AM ModulatorOne of the most popular circuits for amplitude control in oscillators is the soft-limiter circuit (Figure 1a). When the output voltage, VOUT(t), is small, diodes D1 and D2 are off. Thus, all of the input current, VIN(t)/R1, flows through the feedback resistor, R2, and the output...06-07-2018
