It’s difficult to answer because there are no well-defined on or off states for Q3 – it acts like a unity gain voltage buffer and when the resistance between the terminals starts to increase, current through the potentiometer drops and the voltage across it drops hence the source voltage drops and this causes a current to be taken out of C1 and hopefully produces enough of a positive rise in voltage on the output of the op-amp to clock the flip-flop output and turn off the process.
Thank you for your suggestion. If I want to implement the circuit, can I just have a switch connected to CLR without being concerned about the part of the circuit unseen?
Q1’s gate is fed from a flip-flop hence it’s fairly clear that Q1 is used as an enable control for Q4. You may also be interested in: Regarding the switch in red, if the circuit is currently driving current through “wire” and “ring” then closing the red switch will stop that current by turning off Q1 and this in turn simulates the current dropping as per what you say is the purpose of the circuit.
I think I understand why the potentiometer is there. This is your solution of Datasheet of IC search giving you solved answers for the same. Memory Cards, Modules WT I see that as the resistance between the terminals goes up, the source voltage drops.
The device should not be operated at these limits. Andy aka k 10 I am datawheet sure what role the capacitor and switch in parallel with the potentiometer serves. So without knowing the current through “wire” and “ring” and the value if the potentiometer it’s impossible to state what the voltage across them is.
A LOW logic level on the preset or clear inputs will set or reset the outputs regardless of the logic levels of the other inputs. At the time of measurement the clock is grounded. A critical component in any component of a life support device or system whose failure to perform can be rea- sonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness. When Q1 is off Q4’s gate is pulled to 12 volts via R1 and this means that at the source of Q4 is a voltage of around 8 volts to 10 volts.
Freight and Payment Recommended logistics Recommended bank. You can also find Datasheet of IC ppt and other slides as well. I can’t be more precise than this because Q4 is used as a source follower and the voltage it develops at the source is dependent on the gate threshold voltage of that MOSFET and the load current being taken through “wire” and “ring”.

You could use a regularl switch if you need what I think is the “test” feature. The data on the D input may be changed while the clock is low or high without affecting the outputs as long as the data setup and hold times are not violated.
Also, I added one last follow-up question by editing the original post.
The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. Post as a guest Name. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something.
The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock. Email Required, but never shown. Basically, it’s a circuit designed to cut off voltage when electrochemical etching is done.
I looked at the datasheet of DM flip-flop. SeekIC only pays the seller after confirming you have received your order.

Blackwidow 1 It is to introduce a potential value change to the input of the flip-flop. Margin,quality,low-cost products with low minimum orders.
The data on the D input may be changed while the clock is LOW or HIGH without affecting the outputs as long as the data setup and hold times are not violated. Home Questions Tags Users Unanswered. Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and c whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be rea- sonably expected to result in a significant injury to the user.
