Abstract
A pseudo differential current mode receiver includes a regulated cascode buffer for buffering a received data current to generate a buffered data current with cascode-reduced input impedance and cascode-increased output impedance. In addition, a signal converter generates an output signal indicating a difference between the buffered data current and a reference current. The reference current may also be received and buffered by a regulated cascode buffer with cascode-reduced input impedance and cascode-increased output impedance.
Claims27
A pseudo differential current mode receiver, comprising:
- a regulated cascode buffer for buffering a received data current to generate a buffered data current with cascode-reduced input impedance and cascode-increased output impedance;
- and
- a signal converter for generating an output signal indicating a difference between the buffered data current and a reference current.
A pseudo differential current mode transceiver system, comprising:
- a regulated cascode buffer for buffering a received reference current to generate a buffered reference current with cascode-reduced input impedance and cascode-increased output impedance;
- a current mirror that mirrors the buffered reference current to generate a mirrored reference current;
- a plurality of additional regulated cascode buffers, each buffering a respective received data current to generate a respective buffered data current with cascode-reduced input impedance and cascode-increased output impedance;
- and
- a plurality of I-V converters, each converting a difference of a respective buffered data current and the mirrored reference current into a respective output voltage.
A method of processing a data current, comprising:
- buffering a received data current to generate a buffered data current with cascode-reduced input impedance and cascode-increased output impedance;
- and
- generating an output signal indicating a difference between the buffered data current and a reference current.
