Dual voltage high speed receiver with toggle mode

A method for generating dual voltage TM links, comprising:

• receiving an input signal at a first NVT device of a first stage circuit;
• comparing the input signal with a reference signal at a second NVT device of the first stage circuit, wherein the first and second NVT devices are configured to enable a TM between a first supply voltage and a second supply voltage;
• generating a first output signal in response to the compared input and reference signals;
• receiving the first output signal at a second stage circuit;
• generating a second output signal in response to the first output signal converted through a current folding stage of the second stage circuit;
• generating a duty cycle correction to an output signal generated from a duty cycle balancer circuit, wherein the duty cycle correction is configured based on the second output signal, and wherein the duty cycle balancer circuit includes a third NVT device;
• tracking a transconductance with a current source stage circuit based on the output and input signals, wherein the current source stage circuit includes a fourth NVT device, and
• wherein the fourth NVT device of the current source stage circuit is configured to generate a reference current that becomes proportional to the VTH of the first NVT device.
