Programmable sensing adjuster

Abstract

A programmable detection regulator is prepared for serial-connecting master resistance of voltage reference circuit to regulation circuit, arranging multiple regulation resistance being series-connected with master resistance of voltage reference circuit on regulation circuit, parallel each resistance separately to relevant transistor switch being connected to logic controller, connecting logic controller in sequence to detection circuits in numbers equal to transistor switch to decide on-off state of relevant transistor switch for making micro-regulation on master resistance value of voltage reference circuit.

Description

technical field [0001] The present invention is a programmable detection regulator. No matter whether the internal detection circuit of the regulator is actually blown or not, the detection circuit will detect the resistance of the transistor switch and the resistance of the detection circuit. With the increased relative relationship, the logic controller can output "on" or "off" to the corresponding transistor switch according to the detection level signal it receives and cooperate with the logic conversion mechanism. Background technique [0002] At present, the semiconductor industry is moving towards a design-oriented trend, and under the leadership of this trend, the development of 3C integration and system-on-a-chip (SOC) is the hottest, because when the focus is on low price, high performance, and power saving Thin, light, small, and portable can only be achieved with more precise design technology and better manufacturing processes. Today, the number of transistors t...

Problems solved by technology

[0006] 1. The reference voltage generating circuit A of the prior art can only choose to blow out the fuse B2 after the chip is manufactured, and cannot add a new fuse B2. Therefore, in order to achieve positive and negative two-way fine-tuning, all the chips are turned off before processing. All fuses B2 are designed not to blow out (short circuit), so the output voltage A2 of its reference voltage generating circuit A must be low (as shown in Figure 2)

[0007] 2. The fuse B2 of the prior art uses current to perform the blowing action, and when the current is improperly controlled, it will damage the reference voltage generating circuit A, and make the reference voltage generating circuit A useless

[0008] 3. For the above-mentioned detection regulator, because the fuse must be blown to be able to distinguish the logic "0" or "1", the processing needs to be completed on the chip before packaging. If the required logic "0" or "1" cannot be clearly predicted If the setting of 1” is fixed, it is easy to cause the problem of material preparation
