VCO - Búsqueda para electrónicos
By changing the supply voltage fed to a classic 4584 Schmitt trigger type oscillator, the oscillator frequency can be changed over a range of 50:1. A 74HCU04 inverter is used at the output of the 4584 to maintain a constant TTL logic level signal.

The LTC®6951 is a high performance, low noise, Phase Locked Loop (PLL) with a fully integrated VCO. The low noise VCO uses no external components and is internally calibrated to the correct output frequency with no external system support. The clock generation section provides five outputs based on the VCO prescaler signal with individual dividers for each output. Four outputs feature very low noise, low skew CML logic. The fifth output is low noise LVDS. All outputs can be synchronized and set.......

This design is a 2 stage amplifier that has about 17db of gain, suitable for an input of 50 to 100 MW. Its basically a Veronica 5 watt vco transmitter, without the vco. The transistors are a 2N4427 and a MRF237. Output power is 2.5 to 5 watts, depending on input drive and dc voltage. At 13. 7 vdc with 50 MW of drive, the output was 2.5 watts. The maximum dc voltage recommended is about 15-16 volts........

This is the Analog front end of the 80C39 Process Controller. The analog input is protected by a Zener barrier, low leakage. You could use clamping diodes too. The non-inverting low-offset amp offers high input impedance. After further amplification it reaches the VCO LM331. The pulse train from the VCO reaches the uC port and is gated and measured by the MCS48 firmware. The voltage is deduced ........
