$170 | Although sporting 3 knobs and featuring the LM308 chip, this is not a RAT clone, but a variant with deep sonic differences from the original. It has a JFET front-end gain stage that recreates the effect you get when you boost the signal you feed to the RAT, and the voicing...
8.3.1.16 VIN The UCC2897A controller is equipped with a high-voltage N-channel-JFET startup device to initiate operation from the input-power source of the converter in applications where the input voltage does not exceed the 110-V maximum rating of the startup transistor. In these ...
CGD consists of two parts; the first is the capacitance associated with the overlap of the polysilicon gate and the silicon underneath in the JFET region. The second part is the capacitance associated with the depletion region immediately under the gate....
with a 1 µF hold capacitor. The JFET’s have much lower noise than MOS devices used in previous designs and do not exhibit high temperature instabilities. The overall design guarantees no feed-through from input to output in the hold mode, even for input signals equal to the supply...

without having sta-bility problems.Input impedance of 1010Ωallows high source impedances to be used without degrading accuracy.P-channel junction FET’s are combined with bipolar devices in the output amplifier to give droop rates as low as 5mV/min with a 1µF hold capacitor.The JFET’s...
7.13 AM RF AGC control The AM front-end is designed for the application of an external Junction Field Effect Transistor (JFET) low noise amplifier with cascode AGC and PIN diode AGC both controlled by an integrated AGC control circuit. Four AGC thresholds of the detector at the first mixer ...
This circuit accomplishes this using a p-channel JFET (Q6) and a divider resistor (R20). The gate of the JFET is connected to the SS pin (pin 4) of the UCC25600, which is initially low during converter start up. The JFET places the divider resistor in circuit during the period that...
The gate of a JFET must be reverse biased to turn it off and leakage on its output cannot be avoided. MOS switches with gate-protection diodes are preferred in production situations as they are less sensitive to damage from static charges in handling. If used, D1 and R2 should be ...
