Abstract: An amplifier includes a first stage and a second stage. The first stage is configured to amplify a received signal. The second stage is coupled to the first stage. The second stage includes a source follower and a compensation network. The source follower includes an input and an output. The compensation network is coupled to the input of the source follower and the output of the source follower. The compensation network is configured to modify a magnitude and phase response of the first stage based on a load capacitance coupled to the output of the source follower.

Abstract: A device includes a current mirror, a switch, first and second current paths, first and second buffers, a variable resistor, a temperature-sensing circuit, and a controller. The first current path is coupled between the current mirror's input and the switch. The switch switches between ground and a transistor based on a control signal. The second current path is coupled between a first current mirror output and ground. The first buffer is coupled to a second current mirror output. The second buffer is coupled to the variable resistor, which is coupled to the first buffer. The temperature-sensing circuit provides a device temperature to the controller, which is coupled to a first buffer output and determines a first adjustment to the first and second current paths and a second adjustment to the variable resistor based on the device temperature.

Abstract: Described embodiments include a comparator circuit comprising an input voltage terminal, a reference voltage terminal, and a rising edge decode circuit having inputs coupled to the input voltage terminal and the reference voltage terminal. The rising edge output provides a rising edge decode signal indicating the input signal transitioned from being smaller than the reference voltage signal to being larger than the reference voltage signal. A falling edge decode circuit has inputs coupled to the input voltage terminal and the reference voltage terminal, and a falling edge output providing a falling edge decode signal indicating that the input signal transitioned from being larger than the reference voltage signal to being smaller than the reference voltage signal. Also, a decode logic circuit provides a comparator output in response to the rising edge decode signal and the falling edge decode signal.
