APPARATUSES AND METHODS FOR COMPENSATED SENSE AMPLIFIER WITH CROSS COUPLED N-TYPE TRANSISTORS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17662198 titled 'APPARATUSES AND METHODS FOR COMPENSATED SENSE AMPLIFIER WITH CROSS COUPLED N-TYPE TRANSISTORS

Simplified Explanation

The patent application describes an apparatus, system, and method for a compensated sense amplifier with crosscoupled n-type transistors.

  • The sense amplifier includes a pair of p-type transistors that are connected between a system voltage and two gut nodes.
  • When a command signal is active, the p-type transistors are connected in a diode fashion from the system voltage to the respective gut nodes.
  • The amplifier also includes a pair of n-type transistors that are cross coupled.
  • The first n-type transistor has a node connected to the first gut node and a gate connected to the second gut node.
  • The second n-type transistor has a node connected to the second gut node and a gate connected to the first gut node.
  • Each of the n-type transistors may have a separate current flowing through them.
  • There is also a pair of feedback transistors that connect to a ground voltage.


Original Abstract Submitted

Apparatuses, systems, and methods for compensated sense amplifier with crosscoupled n-type transistors. A sense amplifier has a pair of p-type transistors coupled between a system voltage and respective first and second gut nodes. When a command signal is active, the p-type transistors are coupled in a diode fashion from the system voltage to the respective gut nodes. The amplifier also has a pair of n-type transistors which are cross coupled, where a first n-type transistor has a node coupled to the first gut node and a gate coupled to the second gut node and the second n-type transistor has a node coupled to the second gut node and a gate coupled to the first gut node. Each of the n-type transistors may have a separate current flowing through them and respective one of a pair of feedback transistors to a ground voltage.
